The Syrian Observatory for Human Rights documented the killing of 12 members of the Syria’s Fourth Division forces and the regime's intelligence in an ambush by gunmen affiliated with the former leader of the “Abu Tariq Al-Subaihi” factions in the vicinity of Al-Muzayrib town in the western countryside of Daraa.

According to SOHR, military vehicles were targeted at the scene before clashes erupted between the two sides amid huge military reinforcements by the regime forces.

The number of deaths is expected to rise as some of those wounded are in critical conditions, the observatory said.
