This picture taken on Nov. 3, 2014 shows the Mosul Dam on the Tigris River, about 70 km north of the city of Mosul, northern Iraq. Iraqi and Kurdish security forces in August jointly took control of Mosul Dam, Iraq's largest dam, in the country's northern province of Nineveh after battles with so-called Islamic State militants who have been trying to regain the control of this important strategic location.
