Intelligence intercepts picked up chatter between ISIS operatives boasting about taking down an airliner after the Russian Metrojet passenger plane crashed in the Sinai last weekend, killing all 224 aboard, U.S. officials told NBC News Friday.

ISIS operatives in the Sinai and ISIS leadership in Raqqa, Syria, were "clearly celebrating" the takedown of the commercial airliner, one official said. Details about how the plane was brought down were also intercepted, but the officials wouldn't specify what information was shared between the militants.

Another intercept picked up a signal from an ISIS-affiliated group in the Sinai Peninsula before Metrojet Flight 9268 went down. The communications warned of "something big in the area," but didn't specifically mention a plane, officials said.

An adviser familiar the U.S. intelligence said the call was made between members of Wilayat Sinai, which a U.S. official said was one of the "most potent" branches of ISIS.
