The Russian air crash in Egypt was “more likely than not” caused by a bomb, according to the U.K. Prime Minister David Cameron.
Cameron told reporters that while it was not certain that the Russian airliner—which flew out of Sharm al-Sheikh, Egypt—was brought down by a bomb, it was still a strong possibility.
“We cannot be certain that the Russian airliner was brought down by a terrorist bomb, but it looks increasingly likely that that was the case,” said Cameron.
The U.K. has grounded all British aircarft due to fly out out of Sharm al-Sheikh until the security of the airport can be guaranteed. Cameron said it would “take some time” to start flying home an estimated 20,000 British tourists who are holidaying in the area.
The Metrojet Airbus 321 was bound for St Petersburg, Russia, on Oct. 31, when it crashed in Egypt’s Sinai Desert, killing 224 passengers.
