In this video ISIS making their little cub learn how to beheading Christians.

A shocking new video from ISIS shows an angelic-looking blond boy being handed a gun and forced to execute a prisoner in cold blood in Iraq.

The 15-minute video is thought to have been recorded recently in Mosul, in northern Iraq, which the Iraqi Army is hoping to recapture from ISIS this year, Daily Mail reports.

The video, which is entitled 'But If You Return, We Will Return 3' and involves a lengthy narrative about air strikes, was released yesterday on various ISIS terrorist channels.
