The Islamic State (IS) terrorist group beheaded Friday three of its own members in public in the town of Khasham, eastern countryside of Deir Ezzor over banditry and murder charges, the Syrian Observatory for Human Rights reported. On the other hand, U.S.-led coalition warplanes carried out several strikes on oil fields controlled by IS as well as other places around the airbase of Deir Ezzor, with no information about casualties.
