7 people killed and 15 injured, in Bangladesh bus bomb blast
At least 7 people have been burned to death and 15 others injured, some seriously, in a petrol bomb attack on a bus in eastern Bangladesh.
Police said the bus had been full of sleeping passengers when it was attacked near the town of Chauddagram.
It is the latest in a spate of attacks on buses, lorries and cars since anti-government protests began last month.
Opposition leader Khaleda Zia called for the protests on the anniversary of last year's election.
