An Internet video released Friday purportedly shows an Islamic State fighter beheading captured British aid worker Alan Henning and threatening another American captive in the fourth such killing carried out by the militant group.

The video mirrored other beheading videos shot by the Islamic State group, which now holds territory along the border of Syria and Iraq. It ended with an Islamic State fighter threatening a man they identified as an American named Peter Kassig.

“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 in the video says.
