Prosecutors in Bangladesh have demanded that former Prime Minister Sheikh Hasina be put to death over a deadly crackdown on student-led protests last year that ousted her from power, BBC reported.

Hasina, who has fled to India, is on trial for crimes against humanity. According to a leaked audio clip, she ordered security forces to "use lethal weapons" against protesters. She denies the charges.

Up to 1,400 people were killed in weeks of unrest that ended Hasina's 15-year rule. It was the worst violence Bangladesh had seen since its 1971 war of independence, according to BBC.
