British skiers heading to the Alps are being warned by French authorities that off-piste skiing this season is the most dangerous in years.
The season has seen unstable conditions, with 24 people killed so far in avalanches in France and Switzerland, including four this week.
The BBC's Christian Fraser has been to Montgenèvre on the Franco-Italian border to join search teams in training.
The government has introduced restrictions on buying dollars Argentina said citizens can buy up to $2,000 (£1,209) per month if their monthly salary is over 7,200 pesos ($900), after a two-year ban on buying dollars.
But large businesses and investors will not be able to make the purchases.
Last week, Argentina announced the measures after the peso fell 11%, its sharpest daily fall in 12 years.
US dollars could previously only be bought by citizens on the black market, which fuels the country's inflation.
Cabinet chief Jorge Capitanich said only "working professionals, workers and small business owners" would be able to buy the dollars.
Argentines are reportedly reticent about buying US dollars until details emerge about reclaiming a 20% tax rate on the money - which applies if the dollars are stored in the house.
The tax does not apply if citizens store the dollars in a bank account.
Brian Coulton, global emerging markets strategist at Legal and General Investment management, said the government also intervened to devalue the peso, to eight pesos to the dollar, rather than seven.
He said Argentina had also raised interest rates to 6%.
'Not freedom'Rates of inflation in Argentina are some of the highest in the world, as the peso trades at 40% less than its official price on the black market.
The black market is seen as a measure of what people in the country actually think the peso is worth - and a truer indicator of inflation - than the official exchange rate.
The Argentinean government is hoping the controls will bring the official and black market rates for the peso in line.
Mr Coulton said the measures, alongside the devaluation and tightening fiscal and monetary policy, and rising interest rates, should help reduce the country's deficit.
But he added: "Argentina needs tighter monetary and fiscal policy to reduce selling pressures on the peso.
"At present the peso money supply is growing too fast creating inflation and excess demand for dollars at the official exchange rate."
Rodolfo Rossi, an economist in Buenos Aires, said: "This is a relief but it is not freedom. In practice, it gives just a little escape. The pressure on the (black-market peso) is going to continue."
In 2002, millions of Argentines saw their incomes and living standards collapse amid a crisis that included a government default on international debts and 41% inflation.
Large foreign investment projects of this kind are rare in Cuba Brazil and Cuba have inaugurated the first phase of a deepwater sea port, a rare large foreign investment project on the Caribbean island.
The $957m (£577m) overhaul of the port of Mariel, in the west of the capital, Havana, is being financed by Brazil.
It is in the heart of a special economic development zone to which Cuba hopes to lure foreign investment.
The BBC's Sarah Rainsford on the island says the upgrade of the port is the biggest project there for many years.
She adds it marks a major new point in terms of foreign investment, which had been highly limited in Cuba.
The new container terminal is equipped for larger ships passing through an expanded Panama Canal.
It was inaugurated by the Brazilian and Cuban presidents.
'Prosperous future'"Brazil is proud to partner with Cuba in this, which is the first container-terminal port in the Caribbean with the capacity to integrate into the inter-oceanic logistical chain,'' Brazil's Dilma Rousseff said in Mariel.
Her counterpart, Raul Castro, added: "This container terminal, and the powerful infrastructure accompanying it, are a concrete example of the optimism and confidence with which we Cubans see a socialist and prosperous future."
This first phase was financed largely by the Brazilian development bank BNDES and built by the Brazilian construction company Odebrecht.
The terminal will include a rail and highway support network, and replace Havana as Cuba's most important port.
The sleepy town of Mariel, 45 km (28 miles) west of Havana, is best known as the launch point for a mass exodus in 1980, when about 125,000 Cubans left over six months.
A Cuban government decree establishing the special economic zone there includes significant tax and customs breaks for foreign and local companies.
The Caribbean island hopes it will help to increase exports and create jobs.
Arsenal boss Arsene Wenger is to extend his contract with the Gunners, according to chief executive Ivan Gazidis.
The Premier League's longest-serving manager, Wenger is in the final 12 months of his current contract at the north London club.
"Arsene will be extending [his stay] with us and at the right time we will make that announcement," said Gazidis.
Wenger, 64, has been in charge at the Emirates since 1996.
The announcement was made on the same day the Gunners revealed a new multi-million pound kit manufacturing deal with German company Puma.
Last year Gazidis spoke about formalising an extension for his manager, but the move was greeted with protests from some supporters, with the Arsenal Supporters' Trust calling it "inappropriate".
At that time, Arsenal had yet to spend during the 2013 summer transfer window and Wenger's side had slumped to a 3-1 defeat at home to Aston Villa on the opening day of the new season.
However, the Gunners have enjoyed a strong 2013-14 campaign so far and currently sit top of the Premier League by a point, with a goal difference of plus 24 and having won seven of their last 10 games.
In Wenger's 18 years in charge, Arsenal have won three Premier League titles, four FA Cups and four Community Shields, though they have not lifted a major domestic trophy since 2005.
Chilean fishermen could lose out the most from the ruling The United Nations' highest court has redrawn the maritime boundary between Peru and Chile after an acrimonious dispute between the two neighbours.
Judges at The Hague awarded Peru parts of the Pacific Ocean but kept rich fishing grounds in Chilean hands.
At stake were 38,000 square kilometres (14,670 square miles) of ocean and some of the world's richest fishing grounds.
In 2008, Peru asked the International Court of Justice to rule on the matter, saying the border was not legally set.
It wanted the boundary to extend roughly southwest, perpendicular to the point where the two countries' land border meets the ocean.
But Chile insisted it should extend from the coast parallel to the equator.
It cited treaties agreed in 1952 and 1954 which it said had settled the maritime boundary on that basis.
Both countries have pledged to abide by The Hague ruling.
Peruvian ex-President Alan Garcia welcomed the court decision as positive for Peru, saying: "We have gained something and we are happy."
BBC Mundo's Paula Molina in Chile said analysts there see it as the end of tensions between the two neighbours, which have maintained close economic ties despite the long disagreement.
There was a nervous wait in Lima: "In the Hague we are all Peru" read a banner 
Chileans demonstrated ahead of the ruling, who feared conflict could erupt again Peru's fishing industry estimates that the disputed zone has an annual catch of 565m Peruvian nuevo soles ($200m; £121m), particularly of anchovies, which are used to make fishmeal.
Chile has promised financial help to its fishing industry in the event that the court decision affects it adversely.
Correspondents say that, with intense interest in the case in both countries, there was considerable national pride at stake too.
The BBC's Anna Holligan in The Hague says some Peruvians saw the ruling as a chance to win back national pride, and territory, after a humiliating defeat to Chile in the 19th century.
In the 1879-1883 War of the Pacific, Chile took mineral-rich land from two of its neighbours, Peru and Bolivia; the latter lost its only outlet to the sea, which it is determined to regain.
Emin collected her award from Frank Skinner Artist Tracey Emin has been honoured with the South Bank Sky Arts Awards outstanding achievement prize.
Emin, who collected her award from Frank Skinner at the London ceremony, said she was "really overwhelmed".
Arctic Monkeys beat David Bowie to win the pop music prize, while acclaimed ITV crime series Broadchurch triumphed over the BBC's Top of the Lake and The Fall to win TV drama.
British film The Selfish Giant won the film award.
It beat Hanif Kureishi's Le Week-End, starring Jim Broadbent and Lindsay Duncan, and Steve Coogan's Oscar-nominated Philomena.
Coogan was also nominated in the comedy category for Alan Partridge: Alpha Papa, alongside Sky Arts' series Psychobitches.
But both lost out to surprise winner Bridget Christie, who won the prize for her stand-up show A Bic for Her.
Backstage at London's Dorchester Hotel, Christie was genuinely surprised, and said she would place her award - designed by Sir Peter Blake - "on a little windowsill behind a mannequin".
"They put all the cameras on Psychobitches and everyone on my table said 'oh never mind, it doesn't matter'.
"I dealt with not winning and then I quickly had to deal with winning," said the comedian.
She added that the success of her show came after a lull in her work when it "hadn't been going so well".
Emin, 50, is no stranger to collecting accolades after a prominent art career spanning more than two decades.
"It's not about me, it's about art, it's about culture," she said after receiving her achievement award.
Bridget Christie was the unexpected winner of the comedy award, presented by Lenny Henry 
Broadchurch's cast and crew turned out in force to collect their TV drama award "I'm totally focused on what I'm doing at the moment and am very happy," said the artist, who has recently bought a home in Miami.
Emin revealed that her new objectives are to pass her driving test in the US and learn how to speak French, joking that the second ambition is "never going to happen".
Artist Katie Pearson is less of a household name, but walked away with the visual art prize for her work Kettle's Yard in Cambridge and Tipping Point at Wolverhampton Art Gallery.
As well as her Blake trophy, she was given a small conker by artist Gavin Turk, who presented her with her gong.
"It's fantastic! I can't believe it. Winning it is a huge triumph," said Pearson, who graduated from art school in 2007.
"This is not a normal Monday for me. I'm not usually around celebrities. It's a roomful of the most amazing talent".
Episodes star Stephen Mangan presented the breakthrough award to comedian Nick Helm, who stars in BBC Three series Uncle, beating hopefuls from each of the awards categories.
Helm, who has been working the stand-up comedy circuit for more than a decade, said: "Clearly I hadn't broken through yet!"
Asked whether the award would boost his career or provide an inspiration for future projects, Helm joked: "I don't know, I haven't even talked to my mum yet."
Known for his brash comic delivery, he added: "If I can do more work on TV and radio, hopefully it'll mean I won't have to go door to door shouting at people."
Winners Katie Paterson, Nick Helm and Kate Atkinson all collected trophies, designed by Sir Peter Blake 
Darcey Bussell, Daniel May and Dame Kiri Te Kanawa were at the awards gala Life After Life author Kate Atkinson was honoured in the book category, beating The Kills by Richard House and Sathnam Sanghera's Marriage Material.
The National Theatre of Scotland's production of Let The Right One In beat Othello and Chimerica to win the theatre award, presented by Simon Russell Beale.
Winning the opera award was Written on Skin by the Royal Opera House, while the dance category was won by Dracula from the Mark Bruce Company.
The Southbank Centre's The Rest is Noise won the classical music category.
This year's judges included The Observer's Arts Editor Sarah Donaldson, Heat Magazine's Boyd Hilton, The Times Arts Editor Alex O'Connell and the Daily Mail columnist Baz Bamigboye.
The South Bank Sky Arts Awards will be broadcast on 30 January on Sky Arts 1 at 21:30 GMT. The new series of The South Bank Show will begin on the channel in the spring.
Former rebels, mostly Muslims, are being evacuated from military camps The security situation in the Central African Republic is getting even worse despite the inauguration of a new leader, the UN human rights chief says.
"Muslim civilians are now extremely vulnerable," said Navi Pillay.
Her statement came as a Muslim and Christian leader met British Prime Minister David Cameron to lobby for more international assistance.
About a million people - 20% of the population - have fled their homes during months of religious violence.
"I call as a matter of utmost urgency upon the international community to strengthen peacekeeping efforts... Many lives are at stake," said Ms Pillay.
Mobs continue to hunt out Muslim civilians France, the former colonial power, has 1,600 troops in CAR, working with some 4,000 from African countries.
Last week, new President Catherine Samba-Panza said this was not enough.
Since the country's first Muslim leader Michel Djotodia resigned earlier this month, there have been widespread reports of revenge attacks on Muslim civilians.
Members of the Christian majority said they were attacked by members of Mr Djotodia's former rebel group who installed him as leader last year.
But Archbishop of Bangui Dieudonne Nzapalainga and Imam Oumar Kobine Layama, president of the Islamic Central African community, said the unrest was caused by politicians.
"This is not a religious crisis; it's a military-political crisis," Mr Layama told the BBC's Focus on Africa programme.
The two religious leaders warned of a possible famine "We need help for the population, because all our infrastructure is gone, shattered. There is no education, no health care, no medicine," he said before meeting the British prime minister.
"Homes have been razed and famine is on the horizon if we do nothing."
Catherine Samba-Panza was sworn in last week by the interim parliament.
The businesswomen is seen a politically neutral.
CAR is rich in gold and diamonds but years of unrest and poor governance have left most of its 4.6 million people in poverty.
