ISIS Claims to Have Executed British Aid Worker

The Islamic State in Iraq and Syria released a video on Saturday that showed what appeared to be the beheading of a British citizen, David Cawthorne Haines, an aid worker.

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, according to the footage and a transcript released by SITE Intelligence, which tracks the terrorist group.
