Egyptian aviation officials say an EgyptAir flight from Paris to Cairo with 66 passengers and crew on board has crashed.
The officials say the search is now underway for the debris. They say the "possibility that the plane crashed has been confirmed," as the plane hasn't landed in any of the nearby airports.
The officials spoke on condition of anonymity because they were not authorized to speak to the press.
France is offering to send military planes and boats to help search for an EgyptAir flight that disappeared en route from Paris to Cairo.
French Foreign Minister Jean-Marc Ayrault said the government is in constant contact with Egyptian authorities since the plane's disappearance early Thursday.
He said: "We are at the disposition of the Egyptian authorities with our military capacities, with our planes, our boats to help in the search for this plane."
He spoke after French President Francois Hollande held an emergency meeting at the Elysee Palace.
Ayrault confirmed 15 French people were on the flight. "We imagine the anguish of the families."
