MOSUL, Iraq (TNS) -- A pro-government Shiite Iraqi militia said Saturday that it found a mass containing the remains of about 500 people at a prison northwest of Mosul.
Iraqi military forces seized control of Badoush prison from Islamic State this week.
Islamic State took control of Badoush village and the prison complex in June 2014. Human Rights Watch said the group reportedly executed 600 inmates at the prison on June 10, 2014.
Survivors told the rights group at the time that most of those executed were Shiites.
The Sunni radical Islamic State, which regards Shiites as heretics, often targeted Shiite groups and claimed attacks during Shiite religious observances or crowded plaes in mainly Shiite districts.
The Shiite militia, known as the Popular Mobilization group, is politically powerful and have provided crucial backing to government forces.
