August, witnessed the fall of Tabqa airbase into the hands of ISIS (Da'esh), resulting in concentrating their advance to the east to Deir EzZour AFB.

It was left with what couldn't be evacuated of intact but non operational airframes such as the 2217 MiG-21bis and the 1543 MiG-21MF (at least).
Kweres was under siege of ISIS units and was shelled heavily since the mid of August, Hama as well, but by FSyA this time.
