US fighter jets scrambled to intercept Air France flight

An Air France passenger jet flying from Paris to New York has been escorted by two US fighter planes for the last leg of its trip after a bomb threat.

Hours after it landed and was searched, the FBI said no bomb had been found and it declared the Airbus plane clear, CNN reported on Monday.

AF022 landed at JFK airport without incident and was later taken to a special area of the airport for a security check, an Air France official in Paris said.

The anonymous threat was made by phone from the United States, the official said.

The threat claimed chemical weapons were on board the aircraft.

It was a bomb threat phoned in to a Maryland state police barracks shortly after 6.30am, said police spokesman Greg Shipley. The FBI was notified immediately.

Two F-15 planes were scrambled by NORAD, a joint US-Canadian monitoring force, as a precautionary measure, NORAD said.

Once the aircraft was safely on the ground, the US fighters returned to their home base.

The incident came as the United States marked its Memorial Day holiday.

CNN said the US jets were scrambled after US aviation officials tried to contact the pilot of the Air France flight and got no response.
