El Al Flight Gets Swiss Fighter Jet Escort After Bomb Threat

Two fighter jets were scrambled due to a bomb threat on a passenger plane bound for Israel, officials said Tuesday.

Switzerland's air force confirmed that a "sonic boom" heard Tuesday morning was the result of a "hot mission" involving two of its FA-18s. It said in a statement the FA-18s escorted a foreign passenger plane through Swiss airspace, but did not provide details on why.

El Al Airlines confirmed that an "anonymous message" was received about a bomb on board its flight from New York to Tel Aviv, adding that the flight was continuing on to Israel as planned.

An airport spokesman later confirmed the flight had landed safely at Tel Aviv's Ben Gurion airport.

The incident — an apparent hoax — comes amid heightened security at U.S. airports following the deadly attack on Istanbul's international airport.
