Islamic State militants beheaded British aid worker Alan Henning in a video posted on Friday, triggering swift condemnation by the British and U.S. governments.
The footage on YouTube, highlighted on pro-Islamic State Twitter feeds, showed a middle-aged man in an orange jumpsuit kneeling next to a black-clad militant in arid scrubland, similar to past Islamic State beheading videos of two American journalists and a British aid worker.
As in previous videos, Henning appears to read from a script before he is killed. "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," he says.
