Terrorist Group Claims To Have Beheaded US Aid Worker

The video also shows what is believed to be the mass beheading of several Syrian soldiers captured by the group.

The Islamic State group released a video which shows a militant claiming to have beheaded U.S. aid worker Peter Kassig.

The graphic video which was released on Saturday, November 15, 2014, shows the black-clad militant standing over a severed head. It is however not confirmed if Kassig, 26 was pictured in the video. Family representatives were not immediately available for comment, Associated Press reports.

"This is Peter Edward Kassig, a U.S. citizen, of your country; Peter who fought against the Muslims in Iraq, while serving as a soldier," the militant said in the almost 16-minute video.

The video also shows what is believed to be the mass beheading of several Syrian soldiers captured by the group.

Kassig, a U.S. Army Ranger, was providing medical aid to Syrians fleeing the country's civil war when he was captured inside Syria on Oct. 1, 2013. His friends say he converted to Islam in captivity and took the first name Abdul-Rahman.
