By BI: A graphic video out of Iraq was leaked online and alleges to show Iraqi Shia militants burning a tied-up Sunni Muslim over a fire while he screams for help.

HEAVY  The Islamic religious divisions of Sunni and Shia are a major driving force behind the unrest in the Middle East. Sunnis are puritanical in their interpretation of the Quran, while Shia venerates imams much like Catholics venerate saints. Sunnis view this veneration as idolatry and paganic. In the video, the alleged Shias seem jovial over their capture and barbaric killing of a Sunni.
