(AP Photo/PA Wire) (Newser) – ISIS today released another video showing the beheading of a hostage, this time British citizen Alan Henning, reports AP. The video follows the same pattern as the previous three, in which an Islamic State fighter rants against the West. At the end of the video, the militant threatens an American aid worker who has been identified as Peter Kassig, a former US Army veteran who became a volunteer in the Mideast. "Obama, you have started your aerial bombard of Shams (Syria), which keep on striking our people, so it is only right that we strike the next of your people," says the militant. Henning, a taxi driver, was captured in Syria last year while delivering food and water as a volunteer to people affected by the civil war, reports CNN. His wife had pleaded publicly for his release.
