The Islamic State (IS) released a one-minute and eleven-second video titled "Another Message to America and its Allies" on October 3, 2014 showing the beheading of British aid worker Alan Henning and introduced another hostage, Peter Edward Kassig, an American aid worker.
In the video, Henning introduces himself and states, "Because of our Parliament's decision to attack the Islamic state, I, as a member of the British public, will now pay the price for that decision."
Following Henning's statement, a fighter sounds to be the same one from the David Haines beheading video states, "The blood of David Haines was on your hands Cameron. Alan Henning will also be slaughtered, but his blood is on the hands of the British Parliament."
After an edited segment of Henning's beheading, the fighter then introduces Kassig, who states, "Obama, you have started your aerial bombardment in Sham [Syria], which keeps on striking our people. So it is only right that we continue to strike the necks of your people."
