The Islamic State released this short combat footage compilation of their offensive against the Syrian Arab Army in Deir Ezzor. The video also contains images of slain Syrian soldiers (one decapitated) being treated like dirt by the jihadists. The end of the video contrasts previous images by showing slain jihadists in a much more dignified manner.
Among the slain jihadists, according to ISIS, was French national. I think it may have been the guy named Mohammed al-Masri. He had a Twitter account at twitter.com/Muhammad_masry4.
Props to Best Gore member Baby14 for the video:
