The Egypt military believes it has located the wreckage from missing EgyptAir flight MS804.
The plane, carrying 56 passengers and 10 staff from Paris to Cairo, went off radar in the early hours of Thursday morning.
This morning, the airline tweeted: "Egyptian armed forces found in the early hours of this morning after 295km from the coast of Alexandria, the remains of the wreckage of Flight 804 and belongings."
EgyptAir said it wished to extend its "deepest sorrow to the families and friends of the passengers onboard".

This afternoon it added it had found passengers' belongings, body parts, luggage and aircraft seats.
Greek authorities have said the Airbus A320 made two sharp turns and dropped more than 25,000 feet into the ocean.
The cause of the disappearance is not yet known, but Egypt has said the plane was more likely to have been brought down by terrorism than a technical fault.
EgyptAir confirmed there were 56 passengers, including one British, 15 French and 30 Egyptian nationals, on board. Three of the passengers were children, including one infant. Also missing are seven crew members and three security personnel.
The plane had taken off from Paris at 11.09pm local time. It was due to land at Cairo shortly after 3am local time. The pilot had 2,766 flying hours; the aircraft was manufactured in 2003 and had routine maintenance checks carried out in Cairo on Wednesday.
In March, an Egyptair plane bound for Cairo was hijacked and diverted to Cyprus. All hostages were later released unharmed.
And last October a Russian plane flying from Sharm el-Sheikh crashed killing 224 passengers.
