Myanmar security forces took part in the massacre of 10 Rohinyga, the army chief`s office said Wednesday, also admitting for the first time the existence of a mass grave of the Muslim minority in Rakhine state.


"Some villagers from Inn Din village and security members confessed they killed 10 Bengali terrorists," the office said in a Facebook post about the September 2 killings, using a pejorative term for Rohingya.
