Russian military police last week reportedly carried out a raid against Iranian-backed militiamen stationed at Syria’s Aleppo international airport, local media reported.
In the aftermath, several Iranian militia leaders were arrested in what was seen as the latest episode of tensions between Iranian and Russian forces in Syria.
Since the beginning of Syria’s civil war in 2011, Russia and Iran have built a strong military presence in the country in support of forces loyal to Syrian President Bashar al-Assad’s regime.
Iran has since deployed thousands of its Islamic Revolutionary Guard Corps (IRGC) and allied Shiite militias to Syria, while Russia officially entered the Syrian conflict in September 2015 to help Assad’s regime.
But as the war is waning, with Syrian regime forces reclaiming most of the territory once controlled by rebel forces, Russia and Iran seem to be vying for influence in the war-torn country.
