Experts say IS video showing mass beheading of Coptic Christians in Libya doctored

Experts say that the video showing 7 feet tall Islamic State members killing Christians in Libya has been clearly doctored with.

According to FOX News, experts who watched the sickening, five-minute video of 21 Egyptian Coptic Christians being marched along a Libyan beach before being beheaded by black-clad members of IS came to the conclusion that the footage was faked.

Experts say that several anomalies in the video posted online on Feb. 15 suggested that some part of the production was shot in the studio with "green screen" technique.

Veryan Khan, editorial director of the Florida-based Terrorism Research and Analysis Consortium said that the Islamic State's manipulation of their high-production videos has become commonplace.

Khan said the murders likely took place in a studio, and the background image shown was likely from another location, the Bay in Sirte, a part of the Mediterranean Sea on the northern coast of Libya, the report added.
