Radical Islamic extremists release video showing corpses of foreign hostages taken in Nigeria

A video posted online appears to show the corpses of some of the seven foreign hostages abducted from northern Nigeria and later killed by Islamic extremists.

The YouTube video, viewed by The Associated Press on Monday, matched still images released earlier by the Islamic extremist group Ansaru when it claimed the killings.

In the video, a gunman stands in sand, holding a rifle near what appears to be dead bodies. A later shot in the video shows three male corpses, one of whom appears to have been killed by a gunshot wound to the head from a high-powered weapon.

European diplomats confirmed Sunday that the hostages from Greece, Italy, Lebanon and Britain had been killed after their abduction Feb. 16. Nigerian authorities have been silent about the killings.
