NO explosive device has been found aboard an Air France aeroplane that arrived from Chad escorted by the French army following an anonymous threat about the possible presence of such a device, Interior Minister Gerard Darmanin said in a tweet yesterday. "No explosive device has been found aboard the Air France Ndjamena-Paris plane, end of operation", Darmanin said. Air France said earlier in a statement that following the threat, Air France Flight AF865 from N'Djamena to Paris had been escorted by a French Air Force fighter plane and had landed at the Paris-Charles de Gaulle airport.
