Islamic extermists claim to have murdered hostage in Iraq

An extremist group posted a video on a website today showing a man it said was an American hostage being shot in the back of the head, and the German government said one of its citizens released by kidnappers was expected to leave Iraq.

But there was still no word on the fate of four other Western hostages – an American, a Briton and two Canadians – kidnapped in late November.
