Kurdish forces in northern Iraq, backed by US-led coalition warplanes, have launched an offensive to retake the town of Sinjar. A statement from the Kurdish Regional Security Council on Thursday said about 7,500 Peshmerga fighters were closing in on the mountain town from three fronts in an effort to cut off ISIL supply lines. If they succeed, it would effectively cut off the supply line between the ISIL strongholds of Raqqa in Syria and Mosul in Iraq.
