Egyptian investigators say they have identified several locations of wreckage of the EgyptAir flight that went missing over the Mediterranean last month.

A statement said a deep sea search vessel had also sent back the first images of the wreckage.

The EgyptAir flight MS804 was flying from Paris to Cairo on May 19, with 66 people on board when it vanished from Greek and Egyptian radar screens without having sent a distress call.

The Egyptian investigation committee said it would now draw up a map of the wreckage distribution to be able to determine exactly where every single piece of the aircraft ended up.

Investigators are of the opinion that if the plane debris is spread over a large area it tells them the plane broke up in mid-air but if it is more intact, it suggests it hit the water then broke up.

But the wreckage would have to be retrieved for investigators to know exactly what brought down the plane and that could take weeks or even months.
