An Air France flight from Paris was escorted by two U.S. F-15 fighter jets to New York's John F. Kennedy International Airport on Monday after an anonymous threat was made against the flight, the U.S. military said.
Air France flight 22, traveling from Charles de Gaulle Airport in Paris, landed safely in New York, officials said.
Two U.S. Air Force F-15 fighter jets were launched as a precautionary measure to monitor the flight as it approached New York, said Navy Lieutenant Commander Richlyn Ivey, a spokeswoman for U.S. North American Aerospace Defense Command and U.S. Northern Command.
The anonymous threat was made via a telephone call to a Maryland State Police barracks on Monday morning, the police said.
"The caller made a bomb threat involving commercial aviation," the Maryland State Police said in a statement.
ABC News, citing an unnamed senior U.S. official, said the caller made a chemical weapons threat on board the plane.
A spokesman for the FBI's New York office said the plane was escorted to JFK by U.S. Air Force fighter jets "out of an abundance of caution" following a phone threat.
The landed, deboarded and was cleared with no incidents or hazards reported by passengers or crew, said J. Peter Donald, the FBI spokesman.
The New York Post reported 165 passengers and 11 crew members on board the Airbus A-330 though those figures could not be independently confirmed.
Air France could not be reached for comment.
The U.S. military spokeswoman said the command had not received information about any additional threats against commercial airliners.
She also declined to identify which military base dispatched the jets, citing security concerns, but said the jets had returned to the base after the plane landed safely.
It was the first time U.S. fighter planes have escorted a private airplane or commercial aircraft since Feb. 13, when two F-15s followed a general aviation aircraft that was out of communication while flying in a restricted area near San Francisco. The aircraft eventually reestablished communications and was followed by the jets until it landed at Half Moon Bay.
