The search for missing flight MS804 which disappeared from radar screens over the Mediterranean yesterday has entered its second day.
The French foreign minister Jean-Marc Ayrault said there is “absolutely no indication” what brought down the aircraft but terrorism remains the most likely cause.
Flight MS804 was en route from Paris to Cairo with 66 passengers and crew when it vanished early on Thursday.
Greece said radar showed the Airbus A320 had made two sharp turns and dropped more than 25,000ft (7,620m) before plunging into the sea.
Ayrault said: “We’re looking at all possibilities, but none is being favoured over the others because we have absolutely no indication on the causes.”
French President Francois Hollande said: “We will draw conclusions when we have the truth about what happened.
“Whether it was an accident, or whether it was – and it’s something that is on our minds – terrorism.”
