BEIRUT: Islamic State group fighters entered the northeastern Syrian city of Hasakeh overnight, seizing two neighborhoods from government forces in heavy clashes, a monitoring group said on Thursday. At least 30 regime loyalists and 20 IS jihadists were killed in the fighting, which continued into Thursday morning, the Syrian Observatory for Human Rights said. “Heavy fighting is continuing, with shelling by both sides,” Observatory director Rami Abdel Rahman said. He said IS had taken control of two southern districts of the city. “Civilians in those areas and nearby are fleeing to the northern parts of the city,” he added.
