Since the beginning of 2021, Iran has begun working on forming the Hashemiyoon military brigade in Syria, allowing only Shiites to join it. The newly formed faction, which began operating in mid-August, has joined the other pro-Iranian factions in Syria, including Zainabiyoun Brigades, Fatemiyoun Brigade and al-Husseinoun Brigade.
The Hashemiyoon Brigade has engaged in military operations in Syria, with offices and sites spreading through the cities of al-Bukamal, al-Mayadin, Deir ez-Zor and Raqqa in eastern Syria. New offices were also opened in Aleppo and the countryside of Damascus.
