SEPTEMBER 13, 2014
This video shows footage of British Prime Minister David Cameron speaking about Iraq, followed by a message to all allies of America. The man executed is believed to be David Cawthorne Haines, who was previously shown at the end of the ISIS video showing the beheading of Steven Sotloff.

On Saturday afternoon, ISIS released a video purporting to show the execution of a British hostage in the middle of a desert. The video begins with a taped interview of British Prime Minister David Cameron speaking about Iraq, followed by “a message to the allies of America.”

At that point, a masked man holding a knife is showing next to a kneeling man believed to be British citizen David Cawthorne Haines, who speaks to the camera. Haines was reportedly a security manager working in South Sudan for the organization Nonviolent Peaceforce. In the video released Saturday he appears to read a script that blames David Cameron for his execution.

“I would like to declare that I hold you, David Cameron, entirely responsible for my execution,” Haines says. “You entered voluntarily into a coalition with the United States against the Islamic State, just as your predecessor, Tony Blair, did.”

Here is the full transcript of the video:

David Haines – 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.

Executioner – This British man has to pay the price for your promise, Cameron, to arm the Peshmerga against the Islamic State. Ironically, he has spent a decade of his life serving under the same Royal Air Force that is responsible for delivering those arms. Your evil alliance with America which continues to strike the Muslims of Iraq and most recently bombed the Haditha Dam will only accelerate your destruction. And playing the role of the obedient lapdog, Cameron, will only drag you and your people into another bloody and unwinnable war.

Haines is then beheaded. Based on the voice, the styled executioner appears to be the same man in the previous two ISIS videos.

At the end of the video, ISIS members show another British hostage, Alan Henning and threaten his life.

The man who appears to be the executioner says, “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.”
