BREAKING! ISIS Video Shows Steven Sotloff Murdered - FAKE?

The White House is investigating reports of the beheading of US hostage Steven Sotloff by Islamic State militants in a video. He was last seen in Syria in August 2013 until he appeared in a video released online last month by the Islamist group which showed the murder of fellow American journalist James Foley, who was also beheaded. Sotloff appeared dressed in a similar jumpsuit in Tuesday's footage which was entitled A Second Message To America. Sky's Dominic Waghorn said Site, a US video monitoring agency in Maryland, said the video showed Sotloff being beheaded by the same man, believed to be British, who killed Foley. British Prime Minister David Cameron said: "I have just seen the news. It is an absolutely disgusting and despicable act. I will be making a statement later".
