Bangladesh vote begins amid violent opposition protests
The BBC's Mahfuz Sadique says polling stations were widely targeted
Voters are due to go to the polls in Bangladesh amid opposition protests that have left scores dead.
At least 100 polling stations were torched on the eve of the election.
The opposition, which is boycotting the vote, has begun a two-day general strike against what it called a "scandalous farce".
Prime Minister Sheikh Hasina has dismissed their demands for her to step down and a neutral government to oversee the poll, as in previous years.
Bitter enemiesPolice and election officials reported arson attacks at around 100 polling stations in some 20 districts around the country on Saturday, including in the capital, Dhaka.
Many polling stations are based in schools and other civic buildings.
Voting is due to begin at 08:00 local time (02:00 GMT) on Sunday and continue until 16:00.
A government administrator in the south-eastern Chittagong region said there would not be any polls cancelled there as a result of the attacks.
"We've already made a move to shift three polling centres which have been torched by protesters," Mohammad Abdullah told the AFP news agency.
In other violence, police said at least 12 people were injured when a petrol bomb was hurled through the window of a train in the north-west town of Natore.
Security is tight, with some 50,000 troops reportedly deployed around the country for the election period.
The opposition Bangladesh National Party (BNP) began a nationwide 48-hour strike on Saturday a day after its leader Khaleda Zia urged supporters to "completely boycott" what she called a "scandalous farce" of an election.
She accused the government of placing her under house arrest - something the authorities deny.
Not in doubtThe strike is only the latest in a string of protests by the BNP and its allies - including the Islamist Jamaat-e-Islami party - that has seen a blockade of roads, railways and waterways and the closure of shops, schools and offices.
At least 100 people have been killed during weeks of election violence.
Scores of opposition supporters have died in police shootings and dozens of commuters have been burnt to death by protesters throwing petrol bombs at strike-defying buses.
One voter in the capital, Dhaka, Hazera Begum, told Associated Press: "I want to go to vote, but I am afraid of violence. If the situation is normal and my neighbours go, I may go."

The run-up to the election has been marred by outbreaks of violence Analysts say the outcome of Sunday's election is not in doubt.
More than half of the parliamentary seats will be uncontested because of the opposition's boycott, meaning the governing Awami League of Prime Minister Sheikh Hasina will remain in power.
Both the US and the EU have refused to send observers, further raising questions over the electoral process, correspondents say.
All elections since 1991 have been held under a neutral caretaker administration to ensure that voting is not fixed.
But the Awami League abolished the caretaker system in 2010, arguing that it was no longer necessary. It used its two-thirds majority in parliament to make the change.
A special envoy of UN Secretary General Ban Ki-moon came to Dhaka last month with the aim of getting the two sides to talk to each other but the dialogue never got off the ground.
The government has insisted that the BNP should take part in the polls within the existing constitutional framework. It says that the opposition should discuss any changes it wants after the vote.
Sheikh Hasina and Khaleda Zia - who are bitter political enemies - have alternated from government to opposition for most of the past two decades.
