An Air France flight from Paris was escorted by US fighter jets to New York's John F. Kennedy International Airport after an anonymous threat was made against the flight, according to WABC television.
Flight 22 from Charles de Gaulle Airport landed safely, an airport official said.
It was to be taken to a secure area at the New York airport to be searched, according to ABC News.
Citing an unnamed senior US official, ABC News said the Maryland State Police Fusion Center, which handles intelligence gathering, received an anonymous call of a chemical weapons threat on board the plane.
ABC said the threat was not considered credible.
Representatives of the North American Aerospace Defense Command and the FBI, which also were handling the investigation, were not available for comment.
Air France also could not be reached for comment.
