Fighter jets scrambled on Monday to escort Air France Flight 22, an Airbus A-330 out of Charles De Gaulle Airport, to John F. Kennedy Airport, after anonymous threats were made against the flight.

Someone who did not identify himself called the Maryland State Police Fusion Center around 6:45 a.m. Monday morning using from an untraceable number and spoke of a “chemical weapons threat” aboard the flight, ABC 7 reports.

The flight was searched after it landed. In a statement, the FBI said no weapons were found:

Out of an abundance of caution, Air France flight number 22 was escorted to John F. Kennedy airport by U.S. Air Force fighter jets following a phone threat. The plane has landed and has deboarded. There were no incidents or hazards reported on board the flight by either the passengers or its crew. The plane has been cleared.

According to the Guardian, another plane, owned by Saudi Arabian Airlines, was also searched at the airport after a similar threat was made against that flight. The FBI believes the same caller was behind both threats.

Kent Powell, a spokesman for American Airlines, told the Associated Press that a third threat had been made against a flight on that airline flying from Birmingham, England. That threat was later determined not to have been credible.
