The security forces, backed by Shia militias and allied Sunni tribesmen, seized the town of Dhuluiyah, some 90 km north of Iraq's capital Baghdad, and raised Iraqi flags on main buildings in the centre of the town, the source told Xinhua on condition of anonymity. Dhuluiyah is home to the Sunni tribe of al-Jubour, which has been fighting IS militants for several months. The extremist militants seized the town in mid-June, but were driven away from the southern part of the town where the tribesmen's homes are located. The IS militants were holding the northern part of the town and were laying siege to it from the surrounding rural areas.
