About 100 tribesmen fighting under pro-regime militia banner headed Syrian Desert from Qamishli airport on Monday as regime and allied forces wage major offensive against the Islamic State near the Iraqi border, sources said.
The Tribal Mobilization, or al-Hashad al-Ashaeri, was formed in April by regime forces in Hasaka province from the tribes youth. Zaman al-Wasl sources said the total number of the militia reached 3077 fighters.
Regime forces and Iran-backed Shiite militias pressed significant gains against ISIS in the desert, known as Badyia in the last few weeks along the Syrian-Iraqi border and strategic Tanaf crossing.
The regime army also took ground from ISIS in Raqqa province this week.
