Analysis of the debris is likely to be key to determining what happened to the flight.

The images were posted after it emerged the plane sent several warning signals about smoke detected in the jet before it crashed.

One aviation source said that a fire would likely have generated multiple warning signals, while an explosion may not have generated any.

Egypt said its navy had found human remains, wreckage and belongings floating in the sea about 180 miles (290km) north of Alexandria.

A video of the search operation showed a shoe and a handbag among the items floating in the water.

Search crews are scouring for further wreckage, especially the plane's cockpit voice and flight data recorders, commonly known as black boxes.

Planes and vessels from Egypt and five other countries - Greece, Britain, France, the United States and Cyprus - are involved in the search.

The waters in the area are 8,000 to 10,000ft deep, and the pings from the black boxes can be detected up to a depth of 20,000ft.

French Foreign Minister Jean-Marc Ayrault and representatives of Paris Aeroport, the French prosecutor, EgyptAir, and the Egyptian ambassador to Paris met about 100 family members of those on the flight on Saturday.

He said they expressed their "profound compassion" for the victims.

"In the name of France, once more, I am expressing my solidarity, but also our affection...for all those people who learned that a loved one, or even an entire family, have drowned in the sea - and who want to know, to know to be able to grieve".

"It's a difficult moment, a painful moment. I wanted to say it again: We're on their side".

The plane was carrying 66 passengers and crew when it crashed on Thursday.
