As SF reported earlier today, ISIS units have been flanking Syrian government forces deployed west of Palmyra.
So far, ISIS terrorists have seized the Jihad crossroad, the Tyas Mountain north of the Tyas Airbase and the village of Bi’r Marhitan.
The Tyas Airbase will become the next target of the ISIS offensive. If terrorists seize the airbase, the Syrian army’s front will collapse in the area west of Palmyra.
