(BBC News) At least 80 people were killed in Bangladesh on Sunday, amid worsening clashes between police and anti-government protesters.
The unrest comes as student leaders have declared a campaign of civil disobedience to demand that Prime Minister Sheikh Hasina step down.
Thirteen police officers were killed when thousands of people attacked a police station in the district of Sirajganj, police said.
The student protest started with a demand to abolish quotas in civil service jobs last month, but has now turned into a wider anti-government movement.
