ISIS savages shoot down Syrian fighter jet… then mock dead pilot by mounting a model jet to execution tower as they crucify his corpse
WARNING GRAPHIC CONTENT: ISIS fighters shot down a Syrian government jet over the eastern city of Deir ez-Zor. They then hauled out the dead pilot and crucified his corpse, posting the barbaric images on the Internet (pictured). It is known if the jet (inset) was brought down by a missile or came down due to engine failure. ISIS controls most of the eastern province of Deir ez-Zor, but forces loyal to President Bashar al-Assad hold the air base part of the city itself. It comes as Assad accused the United States of not being serious about defeating ISIS.
