Fierce clashes between jihadists and Islamist rebels near Damascus left at least 40 dead and 70 wounded on Friday, a monitoring group said.
The Syrian Observatory for Human Rights said the clashes pitted the Saudi-backed rebel faction Jaish al-Islam (Army of Islam) against Fateh al-Sham, Al-Qaeda's former branch in Syria, and Faylaq al-Rahman, which is backed by Qatar and Turkey.
