Paris says all theories still being examined in EgyptAir crash

French Foreign Minister Jean-Marc Ayrault said today that no theory on the cause of the EgyptAir crash has been ruled out, after revelations of smoke in the cabin minutes before the disaster.

"At this time... All theories are being examined and none is favoured," he told a news conference after meeting with relatives of passengers who were aboard the doomed A320 flying from Paris to Cairo.
