A video released on the internet on October 3, 2014, shows an ISIS fighter beheading British hostage Alan Henning, marking fourth such beheading by the group.
The video was shot in the same way as the other three videos released by Islamic State group. Currently, the ISIS holds territory along the border of Iraq and Syria.
The video ended with a militant from the group threatening a man, which they identified as American named Peter Kassig.
The extremely graphic video meant for mature audience can be watched here.
“Obama, you have started your aerial bombardment of Shams (Syria), which keeps on striking our people, so it is only right that we continue to strike the neck of your people,” the masked militant said in the shocking video, a post on Hindustan Times reported.
Caitlin Hayden, the spokesperson of National Security Council, did confirm that Kassig was indeed held by ISIS.
“At this point we have no reason to doubt the authenticity of the video released earlier today (Friday). We will continue to use every tool at our disposal – military, diplomatic, law enforcement and intelligence – to try to bring Peter home to his family,” Hayden said, according to the post.
