The Islamic State terrorist group says it has executed British aid worker David Cawthorne Haines.
The group released a two and a half minute video purportedly showing Haines being beheaded. Haines, a 44-year-old father of two, was kidnapped last year just three days after he arrived in Syria to work for an international relief agency.
The execution video, entitled "A Message to America’s Allies," emerged shortly after Haines' family issued a public plea for his captors to contact them. In it, his hooded executioner blames British Prime Minister David Cameron for joining forces with the United States against the Islamic State. The executioner warned that the decision will drag the British people into "another bloody and unwinnable war."
Cameron issued a message on Twitter moments after the video was released, calling the murder of David Haines "an act of pure evil." He expressed condolences to Haines' family members who, he said "have shown extraordinary courage and fortitude." Cameron said his government will "do everything in our power to hunt down these murderers and ensure they face justice, however long it takes."
