Armed militants killed 12 Syrian soldiers in an ambush in the southern province of Daraa on Tuesday.

Iran PressMiddle East: "At least 12 members of the Fourth Armoured Division and Syria’s intelligence units were killed in an ambush by militants," the Britain-based Syrian Observatory for Human Rights said.

The soldiers were en route to the al-Mzairib district in the rural west of the province to arrest a former opposition commander when they came under fire by militants loyal to him who sought to thwart his capture, The observatory said.

"The militants attacked two military trucks and two small buses carrying Syrian government forces. That sparked a gunfight that forced Damascus to deploy reinforcements to the area," the office said.

Syrian government forces recaptured Daraa from rebels in 2018. State institutions have since returned, but the army is still not deployed across the whole province, the Observatory says.

Many former rebels stayed instead of evacuating under a Moscow-brokered deal, either joining the army or remaining in control of parts of the province. They were allowed to keep their light firearms.

Al-Mzairib is among the districts controlled by former opposition forces.

Since it came under regime control, Daraa has witnessed a spate of bombings and assassinations targeting government forces, and civilians. Most of them remain unclaimed.

Syria’s war has killed more than 388,000 people and displaced millions since it started in 2011.
