The latest U.S. intelligence suggests that the crash of a Russian passenger jet flying over the Sinai Peninsula in Egypt was most likely caused by a bomb on the plane planted by ISIS or an ISIS affiliate, according to a U.S. official familiar with the matter.
"There is a definite feeling it was an explosive device planted in the luggage or somewhere on the plane," CNN quoted the unnamed official.
In the meantime, the British government is now delaying any flights back and forth in Sharm el-Sheikh. Ireland has also announced that it is suspending flights there despite the Egyptian government's strong statement that the airport security is safe at that airport.
The U.S. is monitoring the ISIS messages searching for claims of responsibility that have not been made public. There were public claims previously which were dismissed by the U.S. government.
