Clashes between Islamic State, Syria rebels kill dozens near Turkey - monitor

BEIRUT (Reuters) - Fighting between Islamic State (IS) and Syrian rebels near the Turkish border has killed dozens of people in the last two days, as IS militants keep up an offensive that has led to rapid territorial gains, a monitoring group said on Saturday.

Fighters from the militant group entered the rebel-held town of Marea early on Saturday, using at least two car bombs in the assault, and clashes continued later in the day, the British-based Syrian Observatory for Human Rights said.
