CAIRO (PIX11/AP) — An Internet video purports to show an Islamic State group fighter beheading British hostage Alan Henning.
The video was released Friday night. It mirrored other beheading videos shot by the Islamic State group, which now holds territory along the border of Syria and Iraq.
The video ended with an Islamic State fighter threatening a man they identified as an American.
The Associated Press could not immediately verify the video's authenticity, though it was released in the same manner as other Islamic State group videos.
In the video, Henning says, "Hi, I'm Alan Henning. Because of our Parliament's decision to attack the Islamic State, I as a member of the British public will now pay the price for that decision."
The black-clad executioner holding him then says, "The blood of David Haines was on your hand, Cameron. Alan Henning will also be slaughtered, but his blood is on the hands of British parliament."
The video then shows the executioner, standing behind Henning, saw quickly at his throat with a knife as the video fades to black. The next shot is a left-to-right pan of Henning's lifeless body, with his severed head placed on top of his back.
Henning, who was a taxi driver in the UK, decided to volunteer in Syria, driving a convoy of medical equipment with his Muslim colleagues to help refugees.
Days ago, Henning's wife Barbara pleaded for his life in an emotional statement:
"Alan was taken prisoner last December by the Islamic State. Allen is a peaceful, selfless man. I cannot see how it assists any state's cause to see a man like Alan dying. I have been trying to communicate with the Islamic State and the people holding Alan, I pray that the people holding Alan respond to my messages before it's too late. When they hear this message, I pray that the people of the Islamic State find it in their hearts to release my husband, Alan Henning."
