Imphal: A court in Manipur Tuesday asked the state government to release human rights activist Irom Sharmila Chanu, who has been on indefinite fast for 13 years demanding revoking of the anti-terror act.

"Ordering her release, a district sessions court observed that the prosecution has failed to establish Sec 309 of the IPC (Indian Penal Code) (attempt to commit suicide) case on Sharmila," a defence lawyer told reporters.
