Intelligence intercepts being used to assess what happened to a Russian airplane that crashed over the Sinai Peninsula came from Israel.
Israeli officials would not comment on the claims by an unnamed U.S. official and a diplomatic source, CNN reported Sunday.
The communications between ISIS affiliates in Sinai were captured by Israeli intelligence focused there and passed along to the United States and Britain, the sources said.
Investigators looking into the crash of the Metrojet flight bound for Russia told Reuters on Sunday that they are “90 percent sure” a bomb on board is the cause. All 224 people aboard were killed in the Oct. 31 crash, including a former program director for Hillel Russia.
The Sinai affiliate of the Islamic State claimed responsibility for bringing down the passenger flight, saying it was in retaliation for Russian airstrikes on rebels in Syria’s civil war.
Russia began launching airstrikes on Syria in September, saying it was coordinating with Syrian President Bashar Assad to combat terror groups such as the Islamic State.
