Egyptian authorities say they have spotted a body part, two seats and suitcases in the search for the missing EgyptAir plane, according to Greek officials.
The announcement on Friday came hours after the Egyptian army announced it had found debris and passenger belongings from the aircraft 180 miles north of Alexandria.
EgyptAir flight MH804 crashed after disappearing from the radar while carrying 66 passengers and crew from Paris to Cairo.
The Airbus 320 lost contact at 2.45 am local time on Thursday morning.
No distress call was made by the pilots and experts believe the crash was most likely the result of a terrorist attack.
The 56 passengers on board included one Briton, 30 Egyptians, 15 French, one Belgian, one Iraqi, one Kuwaiti, one Saudi Arabian, one Chadian, one Portuguese, one Algerian and one Canadian.
The Egyptian presidency has expressed its “deep sadness and extreme regret” over the deaths.
Greece’s defence minister said the aircraft made abrupt turns and suddenly lost altitude before vanishing from radar.
Panos Kammenos said the aircraft was 10-15 miles inside Egyptian airspace and at an altitude of 37,000 feet.
He said: “It turned 90 degrees left and then a 360- degree turn toward the right, dropping from 38,000 to 15,000 feet and then it was lost at about 10,000 feet.”
Search vessels had reported seeing plastic objects including life jackets and seats floating in the sea around 230 miles south of the Greek islands of Crete and Karpathos but they are not believed to be linked to the missing plane.
