Baghdad: Iraqi military investigators discovered two mass graves containing the remains of some 500 decapitated bodies near the city of Mosu.
The two graves were found on Friday near Badoush prison site in the northwest of Mosul, where one contained 470 bodies and the other contained 30, the Joint Operations Command (JOC) said in a statement.
The bodies are believed to be prisoners executed by Islamic State (IS) militants, reports Xinhua news agency.
The Badoush prison is known as the site of an IS massacre of more than 600 inmates on June 10, 2014, when the terrorist group was sweeping the northern province of Nineveh.
