ISIS units reportedly established full control over the pocket southeast of the Abu al-Duhur airbase after all the “moderate rebels” had fled the area or defected to the terorrist group.
Hayat Tahrir al-Sham (formerly Jabhat al-Nusra, the Syrian branch of al-Qaeda) and its allied militant groups used to control a large area in the pocket. However, the rapid ISIS expansion resulted in the collapse of the Hayat Tahrir al-Sham-led forces there.
