Isis fighters backed by tanks and artillery have pushed into an embattled Syrian town on the border with Turkey and taken three districts after heavy street battles with the town's Kurdish defenders.

Hours after the Isis militants raised two of the group's black flags on the outskirts of Kobani, they punctured the Kurdish front lines and advanced into the town itself, the Local Co-ordination Committees activist collective and the Britain-based Syrian Observatory for Human Rights said.
