The government of Bangladesh declared an indefinite nationwide curfew starting at 6 p.m. (1200 GMT) on Sunday, the first time it has taken such a step during the current protests that began last month.
At least 73 people were killed and hundreds injured in clashes in Bangladesh on Sunday, as police fired tear gas and rubber bullets to disperse tens of thousands of protesters calling for Prime Minister Sheikh Hasina to resign.
It also announced a three-day general holiday starting from Monday.
