ISIS Beheads British Aid Worker in Video Message to David Cameron

ISIS released video Saturday evening
that shows the beheading of David Cawthorne Haines, a British aid
worker. Haines' death comes just weeks after the execution of two
American captives, James Foley and Steven Sotloff.

The gruesome video, first reported by the SITE Intelligence Group,
is nearly identical to those showing Foley and Sotloff's executions.
The clip begins with Haines reading a statement blaming British Prime
Minister David Cameron for his death. From the video's transcript:

My name is David Cawthorne Haines. I would like to declare that I
hold you, David Cameron, entirely responsible for my execution. You
entered voluntarily into a coalition with the United States against the
Islamic State, just as you're predecessor, Tony Blair, did. Following a
trend amongst our British Prime Ministers who can't find the courage to
say no to the Americans. Unfortunately, it is we, the British public,
that will in the end pay the price for our Parliaments selfish
decisions.

The executioner, apparently the same man
who killed Sotloff and Foley, then reads a statement, calling Cameron an
"obedient lapdog" who "will only drag you and your people into another
bloody and unwinnable war," and pulls a knife to Haines' throat. The
video then fades to black, before returning to show Haines' severed head
on top of his body.

The video ends with the executioner
threatening to kill a second British hostage, identified as Alen
Henning: "If you, Cameron, persist in fighting the Islamic State, then
you, like your master Obama, will have the blood of your people on your
hands."

Cameron appeared to confirm the beheading later Saturday, calling it an "act of pure evil" in a statement.

Haines
was captured in a small Syrian village in March 2013 while working with
a French group to deliver humanitarian aid. His abduction had been a
secret until the publication of Sotloff's execution video earlier this
month.

Haines is survived by his wife, Dragana, and two
daughters. On Friday, his family released a statement directed at ISIS.
"We are the family of David Haines," the message said. "We have sent
messages to you to which we have not received a reply. We are asking
those holding David to make contact with us."
