During recent weeks Sunni tribesmen from the Syrian province of Deir Ez-Zor have begun a rebellion of their own against ISIS. These Syrian residents were fed up with the hardline religious laws imposed by the Islamic State and actually managed to overthrow the ISIS fighters in at least 3 villages in the countryside of Eastern Syria. To quell the rebellion, ISIS launched a major crackdown on anyone linked to the anti-ISIS uprising. More than 700 tribesmen have been reported killed, with most of the executions being summary decapitations.
This video shows tens of captive tribesmen being beheaded without any sign of mercy shown by the fighters loyal to the Islamic State.
