Syrian government forces have deployed a Russian-made TOS-1A heavy flamethrower system for the ongoing advance on the ISIS-held city of Mayadin in the province of Deir Ezzor.
Mayadin is located in the Euphrates Valley, on the western bank of the river and serves as one of the key ISIS strongholds in the province.
The Syrian Arab Army (SAA) and its allies have already captured many points west and south of the city, including the old airport, the grain silos and the nearby farms.
The TOS-1A system will likely be used to destroy ISIS fortitifications in the area.
