After the announcement of a curfew, thousands of protesters gathered in the Rampura residential area of Bangladesh, and the police shot live ammunition at the demonstrators in the capital, Dhaka, injuring at least one person. The curfew follows one of the bloodiest days in Bangladesh so far during weeks of protests despite a ban on public gatherings, according to the Associated Press. Another 22 people were killed on Thursday when student protesters attempted to enforce a "complete shutdown" of the country. The protests began weeks ago and escalated sharply when violence erupted on Tuesday, marking the biggest challenge for Prime Minister Sheikh Hasina since she won a fourth consecutive term in office after the elections in January, which were boycotted by major opposition groups.
