A new ISIS video was released, threatening the United Kingdom.
FOX's Simon Owen has more from London:
Nine men believed to be responsible for the Paris attacks are featured in the video.
It appears to show them committing atrocities in Syria before they left for France, suggesting they were familiar with killing people beforehand.
Four of the men were Belgian, three French and two Iraqi. They all died in Paris. The video also appears to feature a threat towards British Prime Minister David Cameron.
His office here in London dismissing the recording, calling it the work of a group that is in decline and retreat.
