In Iraq, investigators are probing a mass grave that was discovered by troops advancing towards the Islamic State-held city of Mosul. The discovery was the latest instance of mass graves being uncovered on ground wrested from IS militants.<br/><br/>Footage from the site shows bones and decomposed bodies among scraps of clothing and plastic bags dug out of the ground by a bulldozer in the town of Hamam al-Alil. The militants allegedly killed thousands of people in both Syria and Iraq. <br/><br/>Meanwhile, Kurdish Peshmerga forces continued their push on the town of Bashiqa, about 13 kilometers northeast of Mosul. In a report issued last night, the United Nations said, over 34,000 people have been displaced from Mosul, with about three quarters settled in camps and the rest in host communities.
