"Islamic State" promulgated the video which supposedly shows the ignition timing in the air Russian aircraft Airbus A321 in the sky over the Sinai Peninsula. Yesterday it crashed in Egypt, killing all 224 people on board.
According to Daily Mail, the terrorists claim that their fighters shoted down the plane, but did not indicate how is it possible.
The video shows a blurred figure of aircraft lights in the sky.
Cairo and Moscow denied the possibility of links to terrorism in the incident, which was one of the deadliest accidents in the past decade.
