ISIS beheads second Briton, threatens to kill US war veteran next

ISIS has beheaded British aid worker Alan Henning (left and inset). The militants posted a video of the horrific beheading online last night.
In the video, the executioner who is described as Jihadi John because of his English accent said Alan's blood is on the hands of the British parliament.

Before he was beheaded, Alan also blamed his death on his government. He told the camera

"I am 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.'

He was beheaded shortly after that. ISIS then brought out Iraq war veteran and U.S. citizen Peter Edward Kassig (right) and threatened to kill him next.
