Iran’s Islamic Revolutionary Guard Corps (IRGC) has promoted its drone strikes against the Islamic State near the Iraqi border in Syria. The IRGC says the strikes were carried out as “revenge” for an Iranian soldier who was beheaded by the so-called caliphate.

Bashar al Assad’s forces and allies are advancing on the Islamic State’s stronghold in the eastern Syrian province of Deir Ezzor. The two sides have fought in Deir Ezzor for years and the Assad regime is hoping to turn the tide of battle with the help of Russian airpower.
