Authorities in Myanmar have filed criminal charges against 69 student activists and their supporters who were arrested two weeks ago when police cracked down on peaceful protests against a new education law.

Protesters remained defiant as they sang songs and waved at family and supporters when they were brought in prison vans from Tharyarwaddy prison to Letpadan court on Wednesday morning.

The charges filed against them involve five different counts ranging from hurting a public servant, which carries a maximum penalty of 3 years, to being a member of an unlawful assembly, which carries a 6-month prison sentence.

Police had detained 127 people altogether after the harsh crackdown ended the weeklong standoff on March 10. About 60 people including 28 students and 10 Buddhist monks were freed earlier.
