For the first time since the U.S. President Barack Obama announced an aerial campaign against the Islamic State of Iraq and Al-Sham (ISIS) in Syria, the Anti-ISIS Coalition of predominately Arab states have struck a Syrian Arab Army (SAA) camp in the Syrian province of Deir Ezzor, killing 1 soldier and wounding half dozen others on Sunday evening.

According to a military source from the Syrian Arab Army’s 104th Airborne Brigade of the Republican Guard, a U.S. warplane struck the military camp belonging to the SAA’s 137th Artillery Brigade (17th Reserve Division) in the village of ‘Ayyash, killing 1 soldier instantly and leaving 6 soldiers in critical condition – including an officer.

The Syrian Arab Army’s 137th Brigade has been protecting the civilians in the village of ‘Ayyash from the swarming ISIS fighters that are attempting to break into the provincial capital of the Deir Ezzor Governorate from the northern flank; this airstrike only boosted ISIS’ positions inside this village and the nearby broadcast tower.

As of now; it is not clear who the U.S.-led Anti-ISIS Coalition aircraft meant to target, but it was clear to the Syrian Arab Army soldiers that the airstrikes were inaccurate and lacked logistical comprehension of the ground situation in the Deir Ezzor Governorate.
