Third hostage executed by ISIS
Islamic State militants have released a video to show the beheading of British aid worker David Haines.
BAGHDAD - Islamic State militants fighting in Iraq and Syria released a video on Saturday that purported to show the beheading of British aid worker David Haines.
Haines, a 44-year-old father of two from Perth, Scotland, was kidnapped last year while working for the French agency ACTED.
The video entitled, "A Message to the Allies of America," opened with UK Prime Minister David Cameron talking about working with the Iraqi government and allied Kurdish Peshmerga forces to defeat Islamic State.
"This British man has to pay the price for your promise, Cameron, to arm the Peshmerga against the Islamic State," said a masked man dressed in black with a British accent, standing over Haines, who was shown kneeling and wearing an orange jumpsuit.
The video then showed the beheading of the kneeling man.
At the end of the video, another hostage, identified as Alan Henning, was shown and the masked man said he would be killed if Cameron continued to support the fight against Islamic State.
Cameron condemned the killing and said he would bring the killers to justice.
"This is a despicable and appalling murder of an innocent aid worker. It is an act of pure evil. My heart goes out to the family of David Haines who have shown extraordinary courage and fortitude throughout this ordeal," he said in a statement released by Downing Street.
"We will do everything in our power to hunt down these murderers and ensure they face justice, however long it takes."
U.S. President Barack Obama strongly condemned "the barbaric murder" of Haines and vowed to work with other countries to "destroy this threat to the people of our countries, the region and the world."
"The United States stands shoulder to shoulder tonight with our close friend and ally in grief and resolve," Obama said in a statement. "We will work with the United Kingdom and a broad coalition of nations from the region and around the world to bring the perpetrators of this outrageous act to justice."
In the video, Haines also spoke, saying Cameron was responsible for his execution. "You entered voluntarily into a coalition with the United States against the Islamic State, just as your predecessor, Tony Blair, did," he said.
"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, which will in the end pay the price for our Parliament's selfish decisions."
Foley and Sotloff made similar speeches to Obama, which have been dismissed as scripted by Islamic State and delivered under duress.
The purported executioner appeared to be the same man who appeared in videos with Foley and Sotloff, and it showed a similar desert setting. In both videos, the captives wore orange jumpsuits.
