EgyptAir chairman: Search teams focusing on 65km area
Safwat Moslem, the chairman of EgyptAir, says the current search area has a 65km (40 mile) radius, but it will be expanded if necessary.
Egyptian navy finds more remains and debris
The Egyptian navy says it has found more wreckage from the MS804, including human remains, luggage and passengers' seats.
Earlier today, an Egyptian military spokesperson said wreckage and passengers' belongings had been found 290km (180 miles) north of Alexandria.
In a statement, Egypt's civil aviation 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."
Plane made emergency landing in 2013 after engine fault
The BBC has discovered that the EgyptAir plane that disappeared yesterday had previously made an emergency landing at Cairo airport.
On 25 June 2013, en route from Cairo to Istanbul, as the aircraft was climbing to 24,000 feet, the pilot noticed that the number one engine was overheating.
He decided to turn the aeroplane round and fly it back to Cairo. The official report (in Arabic) says a technical defect was found in the engine and was repaired.
Philip Hammond tweets support to family of British MS804 passenger
The UK's Foreign Secretary, Philip Hammond, has tweeted his support to the family of Richard Osman, the Welsh geologist who was on board MS804.
The lists are often used by both European and US security and law enforcement agencies, said the officials, who spoke on condition of anonymity because they were not authorised to comment on the ongoing investigation, AP reports.
Ex-BA pilot on why MS804 may have made sharp turn
Former British Airways pilot Eric Moody has spoken to the BBC about why MS804 reportedly made two sharp turns before dropping more than 25,000ft (7,620m) and plunging into the sea.
Mr Moody said the sudden 90 degree turn, the first sharp maneuver recorded by military radar, may have been the pilot turning out of the airway - a kind of pathway planes stick to.
"You would turn off because you wouldn’t want to descend ... in case you descended into something coming the other way," he said.
“I would think then something happened and it went totally out of control.”
Gap in air traffic control log 2min, 40sec, not 12 min
Earlier the BBC, and others, reported on an apparent 12 minute gap in the air traffic control log between a failed attempt to contact the aircraft and it disappearing from radar.
But the Greek ATC timeline reported by news agencies appears to have been wrong.
A statement from the Greece's aviation authority (HCAA) says the gap between the first failed attempt to contact the aircraft and it dropping off radar was two minutes 40 seconds.
Here's the full timeline published by the HCAA:
Egypt Air flight MSR 804, A320 en route from Paris to Cairo entered ATHINAI FIR at 02:24 am local time. It was Radar identified and cleared by the competent Air Traffic Controller for the flight path.
At 02:48 am local time, the flight was transferred to the next Area Control Center Sector and was cleared by the ATC for the exit point of ATHINAI FIR. The pilot was jocund and thanked in Greek.
At 03:27 am local time, ATHINAI Area Control Center tried to communicate with the flight for transfer of communication and control from ATHINAI FIR to CAIRO FIR.
Despite the repetitive calls, the flight did not respond and thus the Air Traffic Controller called on the emergency frequency without response.
At 03:29 am local time the flight was over the boundary point, between ATHINAI and CAIRO FIRs.
At 03:29:40 am local time the flight signal was lost from radar, almost 7 NM south/southeast from KUMBI point (boundary point, between ATHINAI and CAIRO FIRs), within Cairo FIR.
Immediate assistance of the Hellenic Air Force radars was requested for possible target tracking, with no avail.
At 03:45 am local time Search and Rescue (SAR) operations were activated through JRCC (Joint Rescue Coordination Center), NAOP (National Air Operations Center) and ADIC (Air Defense Information Center), while updating the Egyptian Civil Aviation Authorities.
Philip Hammond pledges UK support for search
UK Foreign Secretary Philip Hammond has pledged continued support for the ongoing search for wreckage of the MS804.
He said: "We have offered the Egyptian government any support that it requires in searching for wreckage, in analysing anything that is found.
"So far we haven't had any requests but I will be speaking to my Egyptian counterpart in just a few minutes' time."
Families hold 'symbolic' funerals for loved ones in EgyptAir crash
The BBC's Middle East correspondent, Lina Sinjab, who is in Cairo, says some families have already carried out funerals with empty coffins for their loved ones.
She said: "The rituals here are they have to bury the dead as soon as they die, but they are in a really difficult position because they don't know if the bodies would ever arrive, so they're still waiting at the moment.
"They did this as a symbolic move to commemorate their lost ones."
Satellite spots 'potential oil slick' near debris site
The European Space Agency (ESA) says one of its satellites has detected what appears to be a 2km-long oil slick in the eastern Mediterranean Sea – in the same area that Flight MS804 disappeared.
The ESA said it had given information related to the image to the authorities involved in the search.
The agency has been scrutinising satellite data since the aircraft vanished, looking for any clues as to why and where it went down.
According to the satellite image, the slick was at 33°32' N / 29°13' E – about 40 km southeast of the last known location of the aircraft.
Cairo filmmaker posts tribute to four family members
Osman Abu Laban, a Cairo-based Lebanese film director, has posted on his Facebook page to say that he lost four members of his family in the crash - his uncle, aunt, cousin and his cousin's wife.
He posted pictures of the family members and a message praying that they would find peace.
US Secretary of State John Kerry pledges US support
US Secretary of State John Kerry has told his Egyptian counterpart Sameh Shoukry that the US will continue to support the investigation and search for Flight MS804.
The State Department said Mr Kerry offered Mr Shoukry condolences for the lives lost in the plane crash and promised to stay in close contact as the investigation progresses.
Wreckage may be on area of ocean floor 'more like Alps'
Oceanographer Dr Simon Boxall tells the BBC that Flight MS804 went down in a very difficult part of the Mediterranean to search.
"I think the assumption is that this is a shallow water area but it's not, this part of the Mediterranean is really quite deep," he said.
"We only have limited information about the crash location, but if it is where this debris has been found then it sits on a boundary where the ocean floor is more like the Alps, very rugged and contoured.
"That area borders a large, deep plain about 3km down."
Dr Boxall said an aircraft such as the A320 could easily "slip through the cracks" of the ocean floor in the area.
"This is a very soft sediment area and wreckage could sink very quickly, so they need to find it fast," he said.
The ocean floor ridges could also act to block signals from the black box pinger, and sonar from vessels searching for the wreckage, he said.
"Having thought this was a relatively simple one, it could actually be very difficult."
