A man identified in the subtitiles as Al Ghareeb the Algerian speaks at an undisclosed location in this image taken from undated video footage released by the Islamic State, which warned in the new video Monday that countries taking part in airstrikes against Syria would suffer the same fate as France, and threatened to attack in Washington. The video, which appeared on a site used by Islamic State to post its messages, begins with news footage of the aftermath of Friday's Paris shootings in which at least 129 people were killed. | REUTERS / SOCIAL MEDIA WEBSITE VIA REUTERS
