An Iranian proxy militias’ base, in the eastern Syrian city of Deir Ezzor, was hit by airstrikes. The attack killed at least 12 militias, who were reportedly from Iraq and Afghanistan. This attack comes just a few days after an Iranian base in Misyaf was similarly wracked by airstrikes.

The U.K.-based Syrian Observatory for Human Rights (SOHR), reported that unmanned aircraft (drones) launched eight air-to-surface missiles.

The Mezeileh base, just outside of Deir Ezzor, was just reinforced by Iranian-backed Fatemiyoun militia who brought in nearly 30 vehicles carrying troops and military and logistical equipment, coming from the town of Al-Herri on the border with Iraq. Both vehicles and munitions were destroyed in the attack. 

The Observatory didn’t specify the airstrike’s perpetrator, but Rami Abdul Rahman, the head of the SOHR, told the media that Israel was likely responsible for the latest airstrike on the Iranian militias.
