Rebels fight IS-linked group near Israeli-occupied Golan
'Essam al-Rayes, spokesperson for the Southern Front coalition which is fighting Jaish al-Islam, said the IS-linked group had a presence in and around the town of Qahtaniya.
Speaking by phone from Jordan, Rayes said tensions among opposition fighters in the town rose after it was suspected that Jaish al-Jihad had pledged allegiance to IS.
The battles erupted on Monday after Jaish al-Jihad ambushed a Southern Front convoy and killed six rebels, Rayes added.
"Al-Nusra Front then joined the fight, because Daesh is our common enemy," Rayes said, using the Arabic acronym for IS.'
I just listened to an RT report that started off grouping al-Nusra and ISIS together, one of the underlying lies of their pro-Assad propaganda.
