Ahlul Bayt News Agency - The executed person was "Anis Abdullah Bashir" from terrorist group of "Jaish al-Islam" and was responsible for the weapons caches.
This prominent Syrian terrorist was captured by ISIS during regional conflicts in eastern Qalamoun.
By doing this ISIS militants want to deflect the attention from their defeat in Tal Abyad (Syria).
Tal Abyad was being used by ISIS as a key route from Turkey to travel towards its de facto capital Raqqa to the south. Now this strategic town is in "full control" of the Kurdish People's Protection Units (YPG).
