Egypt's civil aviation ministry has confirmed human remains have been found by the country's military in the search for flight MS804.
In a statement, the ministry said: "The Egyptian navy was able to retrieve more debris from the plane, some of the passengers' belongings, human remains, and plane seats. The search is ongoing."
Earlier, the Greek defence minister said the Egyptian military found debris from the missing EgyptAir plane 290km north of the Mediterranean coastal city of Alexandria.
The navy has also found some of the passengers' belongings and is sweeping the area looking for the plane's black box, the military said in a statement.
A European Space Agency satellite has also spotted a potential oil slick in the area.
An image taken by the satellite yesterday afternoon shows a slick about 2km long, roughly 40km southeast of the aircraft's last known location.
A second image taken at 4am today showed that the slick had drifted by about 5km.

Earlier today France's foreign minister said there was "absolutely no indication" what had caused the crash of an EgyptAir flight yesterday, despite Egyptian authorities saying terrorism was the most likely cause.
"We're looking at all possibilities, but none is being favoured over the others because we have absolutely no indication on the causes," Jean-Marc Ayrault told French television.
The French government will meet families of the victims tomorrow in order to "provide all the information we can," Mr Ayrault said.
EgyptAir flight MS804 - an Airbus A320 with 56 passengers and ten crew members from Paris to Cairo - went down about halfway between the Greek island of Crete and Egypt's coastline, after take-off from Charles de Gaulle Airport.
Egypt's aviation minister said yesterday that while it was too soon to say why the plane had vanished from radar screens, a "terrorist" attack would be a more likely scenario than a technical failure.
EgyptAir reported that wreckage from the plane, including life jackets, had been found near the Greek island of Karpathos by Greek authorities.
But EgyptAir's vice chairman Ahmed Adel later told CNN that the items were not from flight MS804.
He said: "We stand corrected on finding the wreckage because what we identified is not a part of our plane. So the search and rescue is still going on."
A British Ministry of Defence spokeswoman this morning said the Royal Fleet Auxiliary landing ship Lyme Bay and an RAF C130 Hercules aircraft had joined the search efforts.
Before it disappeared from radar screens around 2.45am Cairo time (1.45am Irish time), the plane spun all the way around and suddenly lost altitude.
Egyptian and Russian officials said it may have been brought down by terrorists, and there are no signs of survivors.
Civil aviation minister Sherif Fathi said the disaster was still being investigated but the possibility it was a terror attack "is higher than the possibility of having a technical failure".
Alexander Bortnikov, chief of Russia's top domestic security agency, said: "In all likelihood it was a terror attack."
Among those on board were a child and two babies, EgyptAir said.
The airline said the 56 passengers included 30 Egyptians, 15 French, two Iraqis and one each from Britain, Sudan, Chad, Portugal, Algeria, Canada, Belgium, Kuwait and Saudi Arabia.
The Airbus A320 was built in 2003 and was flying at 37,000 feet, the airline said on Twitter.
It tweeted that the pilot had logged 6,275 flying hours, including 2,101 hours on the A320, and the co-pilot had logged 2,766 hours.
There was confusion over whether a distress signal had been sent by the Airbus A320.
Egypt's civil aviation authority said one was received at 4.26am local time, believed to be an automated message rather than one sent by the pilot.
But in a statement on its website, the Egyptian military said later it had received no distress message from the aircraft.
