But Mr Netanyahu reacted defiantly, vowing: "I won't give in to pressure."
There has been little sign of progress from the direct talks that resumed in July after a three-year hiatus.
At the time, Washington said it sought to achieve a deal on a solution to the decades-old conflict by 29 April, but officials say a framework accord on core issues would enable negotiations to continue beyond that date.
'Vital interests'
The BBC's Kim Ghattas in Washington says Mr Netanyahu wants Monday's talks to focus on Iran's controversial nuclear programme.
He believes the US and other world powers are being naive in their negotiations with Tehran, and he is opposed to an agreement that would allow uranium enrichment to continue at low levels.
But Mr Obama is unlikely to budge and is planning to press the Israeli prime minister on peace with the Palestinians, our correspondent adds.
The US president wants both sides to agree to the framework document - not yet made public - proposed by his Secretary of State, John Kerry, which seeks to achieve consensus on core issues.
They include the borders between Israel and a future Palestinian state; the status of Jerusalem; Israel's insistence that it be recognised as a Jewish state; the Palestinians' demand that their refugees be allowed to return to their former homes in what is now Israel; and security arrangements in the West Bank, with Israel wanting a long-term presence in the Jordan Valley.
In an interview with Bloomberg published on Sunday, Mr Obama said he would warn Mr Netanyahu that the "window is closing" for a peace deal.
"When I have a conversation with Bibi [Mr Netanyahu], that's the essence of my conversation: If not now, when? And if not you, Mr Prime Minister, then who? How does this get resolved?" he said, paraphrasing the revered Jewish sage Rabbi Hillel.
If the peace talks failed and there was "continued aggressive settlement construction" in the occupied West Bank, Mr Obama warned, Washington would have limited ability to protect Israel from "international fallout", an apparent reference to the Palestinians' threat to pursue Israel at the International Criminal Court and a boycott campaign.
Mr Obama said Palestinian Authority President Mahmoud Abbas, who will visit the White House on 17 March, was "sincere about his willingness to recognise Israel and its right to exist, to recognise Israel's legitimate security needs, to shun violence, to resolve these issues in a diplomatic fashion that meets the concerns of the people of Israel".
Mr Obama said the negotiations brokered by John Kerry had been "intense, detailed and difficult"
"I think this is a rare quality not just within the Palestinian territories, but in the Middle East generally. For us not to seize that opportunity would be a mistake."
When asked about Mr Obama's comments upon his arrival in Washington on Sunday evening, Mr Netanyahu told Israel's Channel 2 TV: "I won't give in to pressure."
"It has to be a good deal. I will stand up firmly for the vital interests of the state," he added.
Israel's Strategic Affairs Minister Yuval Steinitz meanwhile told Israel's Army Radio: "Netanyahu will, I think, give a clear answer: 'We are ready for peace. We want to advance a diplomatic accord. But we, rightly, worry about and fear for our national security.'"
Israeli officials also blamed the lack of progress on Mr Abbas's refusal to agree to recognise Israel as a Jewish state. The Palestinians have recognised the state of Israel, but say recognising its Jewish character would have implications for Palestinian refugees and Israeli-Arabs.
City workers in Annapolis, Maryland, ploughed snow from the latest storm
A heavy snowstorm has once again created travel havoc on the US East Coast with as much as a foot (30cm) expected to fall in some areas.
Schools were closed across the region, and Washington DC offices of the federal government were shut.
And more than 2,600 flights were cancelled, mostly in New York and Washington DC.
It is the fifth winter snowstorm to hit the eastern US since the beginning of 2014.
"We're tired of it. We're sick of it," Martin Peace, who lives in the Washington DC suburb of Arlington, Virginia, told the Associated Press news agency.
Fast-falling snow clogged up motorways and local roads in the US mid-Atlantic region during the morning and early afternoon on Monday. It had already brought a mix of freezing rain and snow to the Mid-Western states.
About 30,000 homes and businesses in Memphis, Tennessee, were without power after heavy sleet covered the area.
The storm will be followed by near-record low temperatures on Tuesday.
More than 2,600 flights were cancelled on Monday, including many at Washington Dulles airport
As much as 8in of snow was expected in Washington and Baltimore and six inches in Philadelphia by the end of Monday.
Parts of New Jersey and West Virginia could see a foot of snow.
The storm and frigid temperatures have already been blamed for several deaths, including a 13-year-old girl who died when a vehicle overturned on a slick Missouri motorway on Sunday, state police said.
Freeze warnings were in place from the Canadian border to Texas.
Much of Washington DC took a holiday on Monday after the federal government told workers in local offices to stay home.
A group of residents took advantage to stage a mass snow-ball fight on the National Mall, a long park fronting the White House and the Capitol building.
The Washington DC area also saw the worst concentration of flight cancellations on Monday - 80% of flights at Washington's Reagan National were called off.

United Nations Secretary General Ban Ki-moon has urged the Venezuelan authorities to "listen carefully to the aspirations" of protesters and engage in dialogue with the opposition.
His comments came before a meeting in Geneva with Venezuelan Foreign Minister Elias Jaua.
Mr Ban said protesters "must resort to peaceful means in delivering and conveying their messages".
Eighteen people have died in weeks of anti-government demonstrations.
Mr Jaua, who is in Geneva for a meeting of the UN's Human Rights Council, said Venezuela was the victim of a "psychological war" perpetrated by the media.
"The propaganda carried out by some national and international media corporations conveys the wrong idea that there is widespread chaos in our country and indiscriminate repression against the people," he said.
It was aimed, he said, at portraying Venezuela as a country that violates human rights to "justify foreign intervention".
Ban Ki-moon has held talks with Foreign Minister Elias Jaua
After the meeting with Mr Jaua, the UN issued a statement saying that Mr Ban had "reiterated his hope to see reduced tensions and the necessary conditions to engage in meaningful dialogue".
The protests began in the beginning of February in the western states of Tachira and Merida, when local students took to the streets to demand more security after an alleged rape of a local woman.
Many students were arrested. On 12 February, the opposition called for marches in Caracas and other cities to demand the release of all the protesters detained.
Three people were shot dead at the end of marches in Caracas, and police have since arrested five suspects.
The deaths have led to daily protests from the opposition, and clashes have become an almost daily occurrence.
Elias Jaua served as Venezuela's vice-president during the government of Hugo Chavez
Hundreds of people have been arrested, including high-profile opposition politician Leopoldo Lopez.
The opposition blames the government for the violence, but also for failed left-wing policies which, in its view, have led to high inflation, rampant crime and the shortage of many staples in shops.
Government supporters have also taken to the streets in large numbers over the last weeks in rival marches.
President Nicolas Maduro says that right-wing groups backed up by the United States have encouraged the violence as part of a coup plot.
The latest protests in opposition strongholds in eastern Caracas descended into violence
Last week, US Secretary of State John Kerry said he was working with Colombia and other countries to form a mediation strategy for Venezuela's political crisis.
Mr Kerry said it would be "very difficult" for the two sides to come to an agreement without assistance.
Political divisions have deepened in Venezuela after the election of Mr Maduro last April. He succeeded Mr Chavez, who died of cancer after 14 years in office.
Henrique Capriles, who lost the vote by a narrow margin, accused the government of electoral fraud.
The Scottish first minister is to say that Scotland and England will not be "foreign" to each other even if the political union between the two ends.
In a lecture in London, Alex Salmond will insist that cross-border ties of family and friendship will endure if Scotland votes for independence.
He will also claim Chancellor George Osborne's recent speech on sterling was "a monumental error".
The Better Together campaign said Mr Salmond's comments were an "own goal".
The referendum on Scottish independence will be held on 18 September, when voters will be asked the yes/no question: "Should Scotland be an independent country?"
Mr Salmond will describe the referendum as "Scotland's hour" as he delivers the New Statesman lecture, entitled Scotland's Future in Scotland's Hands, on Tuesday evening.
Last month, Mr Osborne ruled out a formal currency union with an independent Scotland, a position that was backed by Labour and the Liberal Democrats.
Mr Salmond is expected to say in his speech: "In the last three weeks people in Scotland have seen an array of approaches from the UK government - what they apparently call their 'Dambusters strategy'.
"We were love-bombed from a distance by David Cameron, then dive-bombed at close range by George Osborne.
"I believe George Osborne's speech on sterling three weeks ago - his 'sermon on the pound' - will come to be seen as a monumental error.
"It encapsulates the diktats from on high which are not the strength of the Westminster elite, but rather their fundamental weakness.
"In contrast, we will seek to engage with the people of England on the case for progressive reform."
Mr Salmond will also renew his criticism of Mr Osborne for suggesting Scotland would be a "foreign" country if voters backed independence.
"Scotland will not be a foreign country after independence, any more than Ireland, Northern Ireland, England or Wales could ever be foreign countries to Scotland," he will say.
"We share ties of family and friendship, trade and commerce, history and culture, which have never depended on a parliament here at Westminster, and will endure and flourish long after independence.
"But the current 'dambusters' rhetoric has betrayed an attitude as antiquated as it is unacceptable.
"From the myopic perspective of the Westminster elite, Scotland is last among equals."
A Better Together spokesman responded: "This speech is a spectacular own goal from the first minister. Not content with telling every expert or employer they are wrong, Alex Salmond now wants to pretend that a poll showing support for separation falling because of his failure to tell us what will replace the pound never happened.
"With poll after poll showing that people living elsewhere in the UK don't support a currency union, the SNP must face up to reality. Rather than engage in his usual name calling and personal attacks, it's time for Alex Salmond to tell the people of Scotland what his Plan B on currency is. Would we rush to adopt the Euro or would we set up an unproven separate currency?
"People in Scotland know that a vote to leave the UK is a vote to lose the strength and security of the pound, with the negative impact that would have on the cost of mortgages, credit card bills and car loans."
Three policemen have been killed in a bomb explosion in Bahrain, the interior ministry has said.
A post on Twitter said the officers had been "dispersing rioters" in the village of Daih, west of the capital, Manama, at the time of the attack.
Witnesses reported hearing a blast during clashes between anti-government protesters and police who were firing tear gas and birdshot to disperse them.
Thirteen police officers have now been killed since protests erupted in 2011.
Last month, one was fatally injured by an explosion on the third anniversary of the start of the uprising that has seen people take to the streets to demand more democracy and an end to what they perceive as discrimination against the Shia community by the Sunni royal family.
Funeral procession
Following Monday's explosion, six leading opposition groups issued a joint statement saying they "regretted casualties, regardless of which side they belonged to".
"The sanctity of blood applies to every human being," it added.
The statement called on opposition supporters to "adhere to peaceful means, and condemn and disclaim criminal acts" and on security forces to "exercise restraint".
The interior ministry said the "terror blast" happened after "police dispersed a breakaway group of thugs who diverted from a funeral route in Daih to riot".
Earlier, people had gathered in the predominantly Shia village for a third day of funeral processions for a detainee who died in hospital last week.
The government and prosecutors said Jaffar Mohammed Jaffar died as a result of complications caused by sickle cell anaemia, which caused a clot to form in his lungs.
Clashes between security forces and protesters erupt frequently in villages outside Manama
His family said he had been subjected to beatings and electrocution since his arrest in December in connection with a seizure of weapons.
Opposition and human rights activists say that in addition to the 13 policemen, more than 80 civilians have been killed over the past three years. However, the government says the death toll is lower.
US urges N Korea restraint after two more test missiles
The missile tests come as the US and South Korean militaries are conducting yearly joint exercises
The US has urged North Korea to exercise restraint after reports it fired two short-range missiles into the sea off its east coast.
US state department spokeswoman Jen Psaki said North Korea should refrain from "provocative actions that aggravate tensions".
South Korean defence officials reported the tests, which came amid joint South Korean-US military exercises.
Pyongyang also test-fired four similar missiles late last week.
South Korean officials said that the missiles launched early on Monday morning were Scud-C models, which have the range to hit any target in South Korea.
Officials in Seoul said the missiles flew more than 500km (300 miles).
North Korea often carries out short-range missile tests to express its anger at its southern neighbour's participation in military exercises.
South Korea and the US began the annual joint exercises on 24 February. The drills, which involve thousands of troops, continue until the middle of April.
Pyongyang is opposed to the drills and has previously called them "exercises of war".
Last year North Korea reacted furiously to the annual military exercises, which came shortly after Pyongyang conducted its third nuclear test, prompting the expansion of existing UN sanctions.
This year, however, ties between the two Koreas have warmed somewhat. Earlier this month, they held reunions for families separated by the division of the Korean peninsula for the first time since 2010.
"The North is taking a double-faced stance by making conciliatory gestures on one hand and pushing ahead with reckless provocation on the other," said South Korea's Defence Ministry spokesman Kim Min-seok.
US President Barack Obama has warned that Israeli PM Benjamin Netanyahu must make "tough decisions" to advance peace talks with the Palestinians.
At the White House, Mr Netanyahu replied Israelis expected him to "stand strong" and that the Palestinians had not done their part to ease tensions.
The White House has said it hopes to see a peace deal in place by 29 April.
But there has been little sign of progress since July, when direct talks resumed after a three-year hiatus.
'Compromise required'
The two leaders spoke publicly on Monday ahead of a bilateral meeting at the White House.
Palestinian Authority President Mahmoud Abbas will visit Mr Obama later this month.
"It is still possible to create two states, a Jewish state of Israel and a state of Palestine, with people living side-by-side in peace and security," Mr Obama said on Monday. "But it's difficult. It requires compromise on all sides."
The US president said the April deadline for the completion of the talks was drawing near, and "some tough decisions are going to have to be made".
"The prime minister will make those decisions based on his absolute commitment to Israel's security and his recognition that ultimately Israel's security will be enhanced by peace with his neighbours."
Sitting beside the US president, Mr Netanyahu pointed to Israel's release of Palestinian prisoners, its withdrawal from Gaza, and other steps it had taken to ease tensions.
"Israel has been doing its part, and I regret to say that the Palestinians haven't," he said.
He demanded the Palestinians recognise Israel as a Jewish state.
And he said, "The best way to guarantee peace is to be strong, and that's what the people of Israel expect me to do: to stand strong against criticism, against pressure."
The meeting between the two leaders came soon after Israel released statistics showing a large increase in the pace of new settlement construction in the West Bank in 2013 over the year before.
'Closing window'
Out of the current round of talks between Israel and the Palestinians, the US president wants both sides to agree to the framework document - not yet made public - proposed by his Secretary of State, John Kerry, which seeks to achieve consensus on core issues.
They include the borders between Israel and a future Palestinian state; the status of Jerusalem; Israel's insistence that it be recognised as a Jewish state; the Palestinians' demand that their refugees be allowed to return to their former homes in what is now Israel; and security arrangements in the West Bank, with Israel wanting a long-term presence in the Jordan Valley.
The Palestinians have recognised the state of Israel, but say recognising its Jewish character would have implications for Palestinian refugees and Israeli-Arabs.
In an interview with Bloomberg published on Sunday, Mr Obama said he would warn Mr Netanyahu that the "window is closing" for a peace deal.
"When I have a conversation with Bibi [Mr Netanyahu], that's the essence of my conversation: If not now, when? And if not you, Mr Prime Minister, then who? How does this get resolved?" he said, paraphrasing the revered Jewish sage Rabbi Hillel.

Suspected militant Islamists have killed at least 29 people in an attack on a town in north-eastern Nigeria's Borno state, a lawmaker has said.
Government troops fled when the militants raided Mafa town on Sunday night, Ahmad Zannah added.
The attack brings to about 150 the number of people killed in Borno since Friday in attacks by the militants and the military, reports say.
The Islamist group Boko Haram is waging an insurgency in Nigeria.
President Goodluck Jonathan declared a state of emergency in Borno and two other states in May, giving the military extra powers to curb the four-year insurgency.
However, Boko Haram has stepped up its violent campaign, with hardly a day going by without reports of a deadly attack by militants, says BBC Nigeria correspondent Will Ross.
Thousand of people have been killed in the conflict and hundreds of thousands have fled their homes.
'Air raid'
Mr Zannah, a senator from Borno state, told BBC Focus on Africa that Boko Haram had warned about a week earlier that it planned to attack Mafa.
Schools were shut and most residents fled to Maiduguri city, about 45km (28 miles) away, he said.
Military reinforcements were sent to Mafa, but soldiers still lacked the firepower or numerical strength to confront the militants, Mr Zannah added.
"When the attack took place, all of them ran away, along with the villagers. There was no resistance," he said.
Maiduguri, the birthplace of Boko Haram, has been badly affected by the conflict
Two policemen were killed by a bomb on Monday morning and fourteen soldiers were missing, Mr Zannah said.
On Saturday night, suspected Boko Haram fighters reportedly destroyed the entire village of Mainok, about 50km west of Maiduguri.
The militants attacked the village with assault rifles, rocket-propelled grenades and explosives, killing 47 people, residents said.
Earlier on Saturday, two bombs killed about 50 people in a densely populated area of Maiduguri - a city which Boko Haram has often targeted.
Borno state senator Ali Ndume told BBC Hausa that about 20 people, many of them elderly, were killed when the army launched an air raid on Daglun village on Friday night.
However, the defence ministry denied the allegation.
"The reports are believed to be part of the design by those bent on discrediting the counter-terrorist mission," its spokesman Chris Olukoladehe is quoted by the AFP news agency as saying.
He said government forces had killed a number of Boko Haram fighters in an operation on Sunday evening, including those believed to have killed at least 29 people in an attack on a rural boarding school in Yobe state more than a week ago.
Boko Haram members suspected to have been involved in the bombings in Maiduguri have also been arrested, Mr Olukoladehe said, AFP reports.
Both the Nigerian army and Boko Haram have repeatedly been accused by rights groups of committing atrocities during the conflict in the region.
China Kunming knife attack: Three suspects captured
As shocked relatives come to terms with the killings, Beijing is certain to argue that the scale and shocking brutality of this attack shows that the threat is real and serious
The three remaining suspects involved in Saturday's deadly mass knife attack in the Chinese city of Kunming have been captured, state media report.
Eight attackers burst into the south-western city's railway station, stabbing people at random, leaving 29 dead and wounding more than 130.
Four attackers were shot dead by police at the scene, officials say. An injured female suspect was reportedly detained.
Officials have blamed separatists from the Xinjiang region for the attack.
Citing a statement from the Ministry of Public Security, Xinhua news agency said six men and two women, led by a person identified as Abdurehim Kurban, were responsible for the attack.
There were no details about how the suspects were identified and captured.
Officials say that evidence, such as insignia and flags about "East Turkestan", points to the involvement of Uighur separatists from Xinjiang - a region in the far west of China bordering Central Asia.
China's security chief, Meng Jianzhu, has vowed "all-out efforts" to "severely punish terrorists".
'Smell of blood'
Eyewitnesses described horrific scenes on Saturday, saying that in just 12 minutes attackers used curved swords and meat cleavers to stab people at random as they rampaged through the station.
A parking attendant at the scene, identified only by his surname, Chen, told Reuters news agency: "I saw five or six of them. They all had knives and they were stabbing people madly over by the first and second ticket offices."
Kunming police and paramilitary forces patrolled an area near the railway station on Monday
A memorial for the victims has been set up at Kunming station, and relatives of the victims have been burning offerings
Chinese leaders also paid silent tribute to the victims at the Great Hall of the People in Beijing
Saturday's attack wounded at least 130, with terrified onlookers abandoning their luggage as they fled
Chen Yugui, a hostel worker who was at the station during the attack, told the paper he saw more than 10 bodies lying on the ground.
"The smell of blood was in the air, and there were lots of people crying," he said.
A memorial for the victims has been set up at Kunming station's concourse.
On Monday, security was tight, with a heavy police presence at Kunming station and surrounding areas.
Kunming is the capital of China's Yunnan province - and it is hundreds of miles away from Xinjiang.
Members of the small Muslim Uighur community in Kunming told Reuters they felt they were under a cloud of police suspicion.
They said that dozens of Uighurs in the Dashuyin district of the city had recently been rounded up for questioning.
Domestic security
Recent months have seen several violent incidents in Xinjiang which the government has blamed on extremists.
Verifying these reports is difficult because foreign journalists' access to the region is tightly controlled.
China is often accused of exaggerating the threat of Islamist terrorism to justify its harsh security crackdown in Xinjiang and the restrictions it places on the religion and culture of the Uighurs.
Beijing is certain to argue that the scale and shocking brutality of this attack shows that the threat is real and serious, correspondents say.
The incident comes a few days before the opening of China's annual parliamentary session, the National People's Congress, where domestic security is expected to top the agenda.
Last October China blamed Xinjiang separatists when a car was driven into a crowd of people on the edge of Beijing's Tiananmen Square, leaving five dead.
Italy's Beppe Grillo given four month jail sentence
Beppe Grillo's Five-Star Movement is the third-largest party in both houses of Italy's legislature
The leader of one of Italy's largest political parties has been sentenced to four months in prison.
Beppe Grillo was convicted of breaking into a sealed-off construction site during a protest against a high-speed train line in 2010.
The former comedian is head of the Five-Star Movement, a protest party which won a quarter of the vote in Italy's last national election.
He will not start his jail term until the appeals process is over.
Mr Grillo was not in court to hear the sentence.
He had admitted entering a hut but denied that he had broken a security seal to do so.
He vowed to fight the sentence, saying after the decision: "Today they sentenced me to four months. I will not give up. Your solidarity really helps".
Nine other activists accused of entering the hut with Mr Grillo were given sentences of up to nine months, while another 10 suspects were found not guilty.
The new high speed railway, known as Tav (Treno Alta Velocita), will run across the Alps between Turin and Lyon.
Supporters say it will slash journey times to Europe and help the local and regional economy.
Opponents say it is unnecessary and environmentally unsound.
Sixty-six jobs go at Pembroke boat firm Mustang Marine
Administrators say they are hopeful of securing a buyer and new owner soon
A boatbuilding and repair firm in Pembrokeshire has gone into administration with 66 job losses.
Mustang Marine, based at Pembroke Dock, says it is is continuing to trade and 48 staff will remain.
Last week bosses confirmed they had managed to stave off closure before Christmas after significant losses on key contracts that had overrun.
Administrators say they are hopeful of "securing a buyer and new owner as quickly as possible".
The firm opened a £1.5m construction hall last November as part of an expansion programme, creating new jobs.
The expansion was hailed as the first major investment in Milford Haven Waterway Enterprise Zone, when Economy Minister Edwina Hart opened the hall.
'Carry on trading'
It has had millions of pounds in funding from the Port of Milford Haven and a cash injection from the Welsh government.
The 66 staff who are being made redundant were told last Friday not to turn up for work today.
Lead administrator Alistair Wardell, head of Grant Thornton's Wales office, said Mustang Marine is currently working on a number of projects, including building a £3m catamaran to service offshore wind farms.
"We have been able to ensure that almost half the skilled workforce will continue at work at Mustang Marine in at least the short term," he said.
"We have received a lot of interest in all parts of the business already and negotiations with those interested parties will continue over the next couple of weeks with the aim of securing a buyer and new owner as quickly as possible.
"In the meantime, a number of parts of the existing business will carry on trading and working on some very exciting projects, which are already under way, thanks to some highly supportive customers.
"We are hopeful of being able to achieve a sale of the Mustang Marine in the very near future."
Founded in Fishguard in 1984, the firm has been based at Pembroke Dock since 1997, where it has been building and supplying boats for commercial use, including pilot boats, wind farm support vessels, workboats and passenger vessels to customers across the world.
Funding package
Mustang Marine interim managing director Stewart Graves said: "The business is going to carry on trading in administration… because we have considerable interest from people who are looking to buy all or part of the business.
"So we are going to keep trading and hope that we are going to be able to find a buyer who is going to be able to secure jobs for the people we have kept on."
Last week, he told BBC Wales the company had a significant cash shortage in December which left it facing closure.
He said with assistance from a new management team and external advisers, a long-term funding package was secured in February from the Welsh government, Port of Milford Haven, and an external third party.
However, after completing its review of the business, the external party withdrew its offer, and "without that party the long-term funding package could not proceed".
Mustang Marine's expansion was said to be the most ambitious part of a phased development in the historic former Royal Dockyard.
In its 200-year history, the dockyard has launched five royal yachts and more than 200 Royal Navy vessels.
Armagh searches over illegal slaughtered meat claims
An investigation is under way into the illegal slaughter of animals in County Armagh
Three properties in County Armagh have been searched following claims that animals are being slaughtered illegally for food.
Two properties in Forkhill and one in Bessbrook were the focus of a coordinated search.
Police, the Department of Agriculture, the Food Standards Agency and Newry and Mourne council were involved.
Police said a suspected illegal animal slaughter and meat cutting operation had been uncovered at Forkhill.
It is understood various items have been removed for examination.
Nothing was uncovered at Bessbrook.
Maria Jennings from the Food Standards Agency, said: "The information we have tells us that meat was being produced illegally, without official hygiene checks.
"We are currently investigating which businesses have been supplied with meat from the plant.
"We will provide further information once we have it."
Chf Insp Davy Beck said the investigation was at an early stage. He said the aim was to address agricultural crime and work with partner organisations to protect the safety of the food chain.
DUP MLA for Newry and Armagh William Irwin said he had received a number of reports about illegal slaughtering.
"I am pleased to see some action being taken on the issue of illegal abattoirs in south Armagh," he said.
"Obviously, the health risks to the public through contaminated meat produce sourced from illegal plants with no hygiene regulations or safety standards and, most worryingly, no traceability in place, could be catastrophic.
"I think all right thinking people will welcome this operation by the police and other agencies today."
Aloysius Hackett murder trial: Son 'knew killing was abhorrent'
Sean Hackett has denied murdering his father Aloysius
A County Tyrone teenager knew that killing his father was an abhorrent act that was morally and legally wrong, Dungannon Crown Court has heard.
Sean Hackett, 19, is on trial for the murder of his 60-year-old father Aloysius at the family home in Augher in January last year.
He has admitted the killing but denies murder.
The jury heard that he clearly understood what he was doing and was acting rationally and logically.
But consultant forensic psychologist Dr Philip Pollock, for the defence, said Mr Hackett was suffering from mild depression that led him to form the irrational belief that killing one of his parents would provide a solution and distraction to his problems, and they would become his guardian in heaven.
Consultant forensic psychiatrist Dr Fred Browne, expert witness for the prosecution, told the jury that Mr Hackett did not display symptoms of depression.
Tyrone GAA (Gaelic Athletic Association) manager Mickey Harte described the teenager as a very talented Gaelic footballer.
'Lovely gentleman'
He said he was one of the best players of his age group who had skill, talent and ability.
He told the court he had his eye on him as a future Tyrone senior player, and had no reason to doubt he would have played at the top level.
Mr Harte had accompanied the defendant when he was granted compassionate bail to attend his father's funeral, and told the court he had visited Mr Hackett three times at Hydebank Young Offenders Centre.
"I found a very quiet, unassuming, lovely gentleman," said Mr Harte.
He said he was the opposite of cold and uncaring, and in his opinion he was very warm and caring.
But the court was told that in the months before the killing Mr Hackett had lost interest in GAA and faked injuries to avoid training, as he said it would have been too hard to leave altogether and lead to too many questions.
He told Dr Browne that the most disturbing thing that had happened to him was breaking up with his girlfriend.
He also found exams stressful and he had drifted away from his friends.
But he did not include killing his father or attempting to strangle his mother in this list of disturbing events.
Charities claim Scotland faces 'humanitarian crisis' caused by poverty
The Scotland's Outlook campaign aims to raise awareness of what it claims are rising levels of poverty across Scotland
A campaign aimed at highlighting the "humanitarian crisis" caused by poverty in Scotland has been launched by a group of charities.
The Scotland's Outlook campaign claimed hundreds of thousands of people were being "battered" by welfare reforms, stagnant wages, rising utility bills, higher living costs and job insecurity.
And it said many families were having to use food banks to feed themselves.
It called on people across the country to "join the fight against poverty".
The campaign is being run jointly by Macmillan, Shelter Scotland, Oxfam, Alzheimer Scotland, Children's Hospice Association Scotland (CHAS), Child Poverty Action Group (CPAG), the Poverty Alliance and the Scottish Council for Voluntary Organisations (SCVO).
It claimed more than 870,000 people in Scotland were living in poverty, with a fifth of children in Scotland living below the breadline and 23,000 people having turned to food banks in the past six months.
Martin Sime, chief executive of the SCVO, said: "With nearly a million people in Scotland living in poverty, we have a humanitarian crisis on our hands and we need everyone's help to tackle it.
"Thousands of people are turning to food banks, struggling to heat their homes, and to clothe themselves and their children. It's not right.
"We want people to wake up to the poverty storm that's engulfing Scotland and get active in the fight against it."
Graeme Brown, director of Shelter Scotland, said: "People across Scotland are being battered by welfare reforms, stagnant wages, rising utility bills, higher living costs and job insecurity.
"Set against the background of 155,100 households on council waiting lists and nearly 40,000 homelessness applications last year, it is clear that much more needs to be done to combat the root causes of poverty if we are to improve the prospects for everyone living in Scotland."
Childcare burden
"We see and hear the misery poverty causes every day. Not only does it have a devastating impact on home life, it has long-term detrimental effects on people's health, wellbeing and life chances - especially children."
The campaign said a key issue was easing the financial burden of childcare in order to make it easier for parents to work.
Hazel, a lone parent living in Fife, said: "I did not want to be a single mum on benefits, like you see on the news. Those mums were portrayed as lazy scroungers and I definitely was not like that.
"I really wanted to work but every way I turned I was hit with barriers and this made accessing employment so difficult. Childcare was so expensive and not readily available in my area."
She added: "I think there needs to be more support for lone parents accessing employment but from an early stage. Childcare needs to be made a priority in all areas, and it should be more affordable and easily accessible."
The campaign will use social media in an attempt to public awareness of the work they are doing to combat poverty across the country.
In a report published last month, the Joseph Rowntree foundation said child poverty in Scotland had fallen at about twice the rate of England over the past 10 years.
And official government statistics released in June said the number of people living in relative poverty had fallen slightly, from 780,000 in 2010/11 to 710,000 the following year.
But the figures from Scotland's chief statistician also showed there had been a fall in the average household earnings in Scotland, from £461 per week to £436, over the same period.
Michael Piggin: Terror offences accused can be named
Michael Piggin is alleged to have possessed nine partially-assembled petrol bombs, firework powder and partially-constructed improvised explosive devices
A judge has lifted an order banning the naming of an 18-year-old man charged with terror offences.
Michael Piggin, of Loughborough, is accused of possession of items for the purpose of terrorism, including partially-constructed pipe bombs.
He is also charged with possessing a document containing information likely to be useful for a person committing or preparing an act of terrorism.
Mr Piggin denies the two charges and his trial is due to begin on Tuesday.
Mr Piggin is alleged to have possessed nine partially-assembled petrol bombs, firework powder, partially-constructed improvised explosive devices, a crossbow, a variety of air rifles, a gas mask and stab proof vest.
He is also charged with having a notebook containing information about the planning of attacks and the construction of explosive devices.
Mr Piggin, whose name could not previously be reported owing to his age, is due to stand trial at the Old Bailey in London.
Prison officer Julie Turton jailed over sex and drugs
Julie Turton was sacked by HMP Birmingham when she was charged with misconduct
A prison officer who had sex with an inmate and supplied drugs to prisoners at HMP Birmingham has been jailed.
Julie Turton, 54, of Hamstead, Birmingham, admitted misconduct in a public office and was sentenced to 32 months at Birmingham Crown Court.
The court heard she supplied inmates with cannabis that was smuggled into the prison inside two chocolate eggs.
The judge said her sexual relationship with drug dealer Danny King had caused "serious risks to security".
The court heard Turton was in charge of staff and up to 160 inmates on M wing at the prison, known as Winson Green, between November 2011 and May 2012.
During that time she admitted calling and texting three inmates more than 900 times, including King, the court heard.
Those contacted also included Arteef Hussain, 25, now at Stoke Heath prison.
Cannabis was smuggled into the prison inside chocolate eggs, the court heard
Hussain was sentenced to a further 12 months after admitting encouraging Turton to supply cannabis while he was an inmate in Birmingham.
'Reckless'
Defence lawyer Jonathan Park told the court Turton had been depressed after discovering her husband had had an affair and "was manipulated".
Arteef Hussain pleaded guilty to encouraging Turton to supply cannabis
She had "no sinister motive for her misconduct", he said.
Judge Thomas Rochford said Turton's "special link" with King and inappropriate friendships with others "defied belief".
He said: "[You knew] that your sexual relationship was bound to cause serious risks to security and to discipline."
HMP Birmingham sacked Turton when she was charged with misconduct.
Director Pete Small said her behaviour had been "reckless".
He said: "As an established prison officer with more than 20 years of experience, Julie Turton not only let herself down, but abused the trust of her colleagues and the prison service."
The 86th Academy Awards have taken place in Hollywood.
U2 performed their song from Mandela: The Long Walk To Freedom at the ceremony, and the BBC's Colin Paterson was keen to track down the band's lead singer, Bono.
First broadcast on BBC Radio 4's Today programme on Monday 3 March.
Historical drama 12 Years a Slave has won best picture at the 86th Academy Awards, while space drama Gravity won the lion's share of awards.
Gravity's Alfonso Cuaron became the first Latin American to win the best director award, adding to the film's six Oscars for technical achievement.
Cate Blanchett was named best actress for her portrayal of the heroine in Woody Allen's Blue Jasmine.
Matthew McConaughey won the best actor Oscar for Dallas Buyers Club.
It is the second consecutive year the best director and best picture prize have been awarded to different films.
Cuaron praised the "transformative" power of film and singled out the film's star Sandra Bullock as "the soul, the heart of Gravity".
Cuaron won two Oscars, for direction and film editing. He co-wrote the screenplay with his son Jonas
The film - which took five years to complete, and owes much to the technical prowess of British visual effects specialists - also won Oscars for film editing, sound mixing, sound editing, cinematography, visual effects and original score.
Steve McQueen, the British director of 12 Years a Slave, dedicated the best picture Oscar to "all those people who have endured slavery".
"Everyone deserves not just to survive, but to live," he said. "This is the most important legacy of Solomon Northup."
Based on a true story, it follows the life of a free black man - Northup - who is kidnapped and sold into slavery in Louisiana.
Producer Brad Pitt praised "the indomitable Mr McQueen" - a Turner Prize-winning artist-turned-director - for "bringing them all together" to tell Northup's story.
Lupita Nyong'o also picked up an Independent Spirit Award on Saturday for her role in 12 Years a Slave
Newcomer Lupita Nyong'o won the best supporting actress award for her film debut as slave worker Patsey.
The Kenyan actress paid tribute to her character and thanked her for her "guidance". "It doesn't escape me for one moment that so much joy in my life is thanks to so much pain in someone else's," said the star, who turned 31 this weekend.
The film won a third Oscar for John Ridley's adapted screenplay. "All the praise goes to Northup," Ridley said. "These are his words."
In other developments:
Host Ellen Degeneres broke a Twitter record with a "selfie" from the Oscar audience.
American Hustle and Wolf of Wall Street were left empty-handed, despite 15 nominations between them.
Jennifer Lawrence fell over on the red carpet. The star had also tripped up as she collected the best actress prize at last year's ceremony.

'Taught to dream'
Spike Jonze collected the best original screenplay for Her. Jonze's first film as sole writer and director stars Joaquin Phoenix as a man who falls in love with a computer operating system, voiced by Scarlett Johansson.
As predicted, McConaughey took the best actor prize for his role as Ron Woodroof, a real-life rodeo cowboy who smuggled HIV drugs into the US.
The 44-year-old actor, formerly a rom-com regular whose roles centred on his good looks, lost 50lbs (23kg) to play Woodroof in the low-budget indie drama.
During his speech, he thanked God "because that's who I look up to".
"He's graced my life with opportunities that I know are not of my hand or any other human hand," he added.
Jared Leto won for his role as a transgender woman in Dallas Buyers Club
Best actress winner Blanchett paid tribute to her rivals, including Dame Judi Dench - who was not at the ceremony - acknowledging "the random and subjective" nature of awards ceremonies.
McConaughey's co-star Jared Leto won the first Oscar of the night, picking up best supporting actor for his role as a transgender woman who becomes Woodruff's business partner and unlikely friend.
In an emotional speech Leto thanked his mother, who accompanied him to the awards, "for teaching me to dream" and dedicated his award to "those who have ever felt injustice because of who they are, or who you love".
"This is for the 36 million people out there who have lost the battle to Aids," said the 30 Seconds to Mars frontman, whose last film was six years ago.
Blanchett, who was presented with her Oscar by Daniel Day Lewis, had a long list of thank yous
Dallas Buyers Club also picked up a third award for make up and hairstyling - with the transformation of Leto and his co-star, Matthew McConaughey, rumoured to have been achieved on a budget of $250 (£150).
Frozen, which recently tipped $1bn (£600m) at the global box office, scored two Oscars.
The 3D film about an icy princess and her sister was named best animated feature film, with its song, Let It Go - performed by star Idina Menzel - winning best original song. It is loosely based on The Snow Queen by Hans Christian Andersen.
The Great Gatsby also picked up two Oscars, for costume design and production design. The awards were picked up by Baz Luhrmann's partner Catherine Martin.
But there were no awards for David O Russell's American Hustle, which had 10 nominations, including nods in all the acting categories. Nor were there any awards for Martin Scorsese's The Wolf of Wall Street.
The first British win of the night came for Tim Webber and his team from London-based company Framestore for their visual effects work on Gravity.
Webber paid tribute to his team, Gravity actors George Clooney and Bullock and director Cuaron "for having the vision to create this breath-taking film and the audacity to make it happen".
The second British win of the night went to director Malcolm Clarke, who won an Oscar for his documentary short The Lady in Number Six: Music Saved My Life.
The film follows Alice Herz-Sommer, the oldest known survivor of the Nazi Holocaust and an accomplished pianist. Paying tribute to Herz-Sommer, who died last week at the age of 110, Clarke praised "her extraordinary capacity for joy and amazing capacity for forgiveness".
"She taught everyone on my crew to be a little bit more optimistic," he added, dedicating his award to her.
Ellen DeGeneres hosted the ceremony, for the second time, at the Dolby Theatre in Hollywood.
A growing reliance on crops like wheat help feed a growing population - but at what cost?
Fewer crop species are feeding the world than 50 years ago - raising concerns about the resilience of the global food system, a study has shown.
The authors warned a loss of diversity meant more people were dependent on key crops, leaving them more exposed to harvest failures.
Higher consumption of energy-dense crops could also contribute to a global rise in heart disease and diabetes, they added.
The findings appear in PNAS journal.
"Over the past 50 years, we are seeing that diets around the world are changing and they are becoming more similar - what we call the 'globalised diet'," co-author Colin Khoury, a scientist from the Colombia-based International Center for Tropical Agriculture, explained.
Other crops provide the supplementary nutrients to diets that the major staple foods cannot deliver
"This diet is composed of big, major cops such as wheat, rice, potatoes and sugar.
"It also includes crops that were not important 50 years ago but have become very important now, particularly oil crops like soybean," he told BBC News.
While wheat has long been a staple crop, it is now a key food in more than 97% of countries listed in UN data, the study showed.
And from relative obscurity, soybean had become "significant" in the diets of almost three-quarters of nations.
He added that while these food crops played a major role in tackling global hunger, the decline in crop diversity in the globalised diet limited the ability to supplement the energy-dense part of the diet with nutrient-rich foods.
Amid the crops recording a decline in recent decades were millets, rye, yams, sweet potatoes and cassava.
The study by an international team of scientists also found that the homogenisation of the global diet could be helping accelerate the rise in non-communicable diseases - such as diabetes and heart disease - which are becoming an increasing problem worldwide.
Crop failure fears
Fellow co-author Luigi Guarino, from the Global Crop Diversity Trust, added: "Another danger of a more homogeneous global food basket is that it makes agriculture more vulnerable to major threats like drought, insect pests and diseases, which are likely to become worse in many parts of the world as a result of climate change.
"As the global population rises and the pressure increases on our global food system, so does our dependence on the global crops and production system that feeds us.
"The price of failure of any of these crops will become very high," he warned.
Last month, the European Parliament adopted a resolution that called on EU nations to adopt measures to preserve crops' biological and genetic diversity in order for plant breeders to provide adaptable varieties of crops that will be able to cope with projected climatic changes and the need to increase yields.
MEPs said they were concerned that the global plant breeding market was currently "dominated by just a few large multinational undertakings which invest only in a limited number of varieties".
They added that estimates from the UN Food and Agriculture Organization (FAO) suggested that "the diversity of cultivated crops declined by 75% during the 20th Century and a third of of today's diversity could disappear by 2050".
In order to improve the resilience of the global food system to future shocks, Mr Khoury said an expansion in the diversity of the globally important crops was needed.
"We also need to ensure the the genetic diversity is available to people," he suggested.
"That diversity comes from old varieties and the wild species that are related to the crops.
"A good example is if you are a breeder of maize (corn) in southern Africa where the crop is the main staple, then the diversity you will want will typically come from where the crop originated, which is Mesoamerica (Mexico to Belize).
"It is important already and will be increasingly important in the future that the people producing varieties suitable for southern Africa actually have access to varieties from Mexico."
