New ISIS video shows Paris attackers committing prior atrocities, threatening UK

(FoxNews.com) - A new video released by the ISIS terror group late Sunday shows nine of the extremists who carried out the Nov. 13 attacks in Paris beheading and shooting captives, as well as training with weapons while plotting the carnage that left 130 dead in the French capital.

The 17-minute video shows the extent of the planning that went into the multiple attacks in Paris, which French authorities have said from the beginning was planned in Syria. The video was provided online by the SITE Intelligence Group, which monitors jihadi websites.

The video does not contain any footage of the attacks themselves, but is assembled from material shot before the men left for Paris, as well as news and amateur videos. The video did not specify where the nine men were filmed, but it was believed to have been in ISIS-controlled territory in Syria.

The video also contains threats against the United Kingdom, showing images of London landmarks Tower Bridge and St. Paul's Cathedral and claiming extremists are ready to strike "anytime, anywhere." At one point, the image of British Prime Minister David Cameron is shown with a crosshair over his face.
