The Islamic State in Iraq and Syria-ISIS released a video on Saturday that showed the beheading of a British citizen, David Cawthorne Haines, an aid worker.
The 44-year-old Haines was abducted in March 2013 near a refugee camp in Atmeh, Syria.
He is seen kneeling on a bare hill in a landscape that appears identical to the one where two American journalists were killed by the group in back-to-back-executions in the past month,
Moments before his death, Mr. Haines read a script in which he blamed his country’s leaders for his killing. Addressing Prime Minister David Cameron of Britain, he said, “You entered voluntarily into a coalition with the United States against the Islamic State, just as your predecessor Tony Blair did, following a trend among our British prime ministers who can’t find the courage to say no to the Americans.”
