AFP, BEIRUT: US-led aircraft bombed Islamic State group fighters battling rival rebels including Al-Qaeda loyalists in northern Syria overnight, a monitoring group said on Sunday. The Syrian Observatory for Human Rights described the raids in Aleppo province as intervention on the side of the rival rebels, even though they include forces that have previously been targeted by US-led strikes. "The coalition carried out at least four strikes overnight targeting IS positions in the town of Suran," the Britain-based group said. "It's the first time that the international coalition has supported non-Kurdish opposition forces fighting the Islamic State," said director Rami Abdel Rahman. He said at least eight IS fighters were killed in the strikes. IS seized control of Suran a week ago, and has since been fighting an alliance of Islamist rebels.
