Ah okay I misunderstood because you called it desperate.
As for why; PKK arrested people from their tribe (Arab). Theyre clearly sick of PKK and their actions against the people of Manbij.
TSK and FSA are advancing from behind the main YPG/PKK defense in East Afrin and also towards important Minakh (city with airbase) and Tal Rifaat.
Quickly made this :p
Biggest weapon/ammo depot captured so far:
This is a group called "Jaish al-Thuwar" or "JAT" they are basically traitors to the FSA and their cause, but they continue to use the FSA flag. This group allied with the YPG/PKK to form the SDF. These traitors even wanted to form a military council for Idlib, their plan was to invade Idlib...
