Russian Airliner Probably Destroyed By Bomb

The Daily Mail has cited to multiple sources and news agencies as reporting that the Russian Metrojet airliner was brought down with a bomb. From the story:

A US intelligence source has claimed a bomb planted by ISIS or an ISIS affiliate is the most likely reason behind the Russian jet crash in Egypt last Saturday.

Intelligence agencies have preliminary evidence suggesting a bomb brought down the plane, killing all 244 people on board, a US official said.

They added that intercepted communications point to an ISIS affiliate in Sinai being responsible for the mid-air blast.

Another security source told CNN there was a 'definite feeling it was an explosive device planted in luggage or somewhere on the plane'.

Investigators are focusing on ISIS operatives as the bombers, another US official told NBC News today.

Not confirmation, obviously, but probably correct.
