Bangladesh’s army chief is due to address the nation this hour at a time of widespread unrest and deaths.
On Sunday, at least 97 people were killed during violence between government supporters and those who want her out.
Students are marching on the capital Dhaka, to demand justice for 300 people killed since last month.
An indefinite curfew has been put in place – the internet has been cut-off, and offices and factories closed.
Students began protesting last month when a controversial job quota system that favoured children of war veterans was reinstated by the high court. That has since been scaled down by the country’s top court.
