Captured, bound with a rope around his mouth and crucified: Rebels turn the tables on ISIS and torture seized jihadist

Graphic images appear to show an ISIS fighter being tied up before he was executed by a rebel group in Syria.

Social media accounts who document terror-related news claim he was captured in the northern Aleppo region, and and later crucified.

Two leaked pictures show the extremist, who may already be dead, bound by a rope which tightens across his chest and open mouth as a group of unidentified men surround him.
