The Britain-based Syrian Observatory for Human Rights said late yesterday that the al-Qaida linked Islamic State in Iraq and the Levant killed 26 people in yesterday attack, near the base of a rival rebel group.
The Syrian rebel group, known as the Tawheed Brigades, confirmed the attack on Twitter, saying in an interview they posted that their commander, Adnan Bakour was killed.
A coalition of rebel groups has for weeks been fighting the Islamic State, a group resented by many rebels for its perceived arrogance and extremism.
