Quote Message"I absolutely feel for them [the families]. This is obviously a dreadful event. One of our ships, RFA Royal Fleet Auxiliary Mounts Bay, is nearby and so we've sent it to the area but I think it's too early to speculate about what the cause was. All the experts are talking to each other and trying to work out what has happened and when we know more, we'll be able to say more."

If you are just joining us, here is a recap of the latest developments:
Wreckage of the missing EgyptAir flight has been found near Karpathos island, the airliner says.
In a statement, EgyptAir says the confirmation has been made by Egypt's Ministry of Foreign Affairs to the country's Ministry of Civil Aviation.
The Reuters news agency, quoting the Egyptian civil aviation ministry, reports that Greek Authorities have found "floating material" likely to be debris and life jackets from the EgyptAir plane.
The White House says it is too soon to say what caused the MS804 aircraft to go down. At a press briefing, a spokesperson extended the US's condolences to victims' families and offered to help the authorities who are investigating the crash.
He said the US is aware that extremists want to attack the aviation system, and the country is constantly adapting its tactics, Reuters reports.
EgyptAir Vice President has told the American broadcaster CNN that the wreckage of the missing flight has been found, CNN's Christiane Amanpour tweets.
EgyptAir's official Twitter account said earlier that the information was not confirmed.
A former civil aviation minister from Egypt has said the suggestion that the EgyptAir plane swerved sharply before crashing means something must have happened to force the pilots to lose control.
Mustafa Kamel was speaking to the Associated Press news agency.
He said that if the black box is recovered, that might help uncover what that was.
Mr Kamel said passenger planes were not designed to make abrupt turns while flying.
He said: "These are not warplanes."
Quote MessageWhat I would say out of experience is this sudden disappearance of the flight means the plane either exploded in the air, or plunged into the sea. No matter what the cause is, there was no indication. It happened all of a sudden.

A Royal Air Force Hercules aircraft from Akrotiri base has joined the search for the missing EgyptAir plane, the BBC's defence correspondent Jonathan Beale reports.
France has announced it is sending investigators and technical expert to help in EgyptAir probe, the AFP news agency reports.
The BBC's James Reynolds is at Charles de Gaulle airport, in Paris, and says it is a "normally operating airport", despite the uncertainty over the EgyptAir flight that disappeared earlier while en route from Paris to Cairo.
He adds there are soldiers walking with guns but that people are still carrying on with their plans.
"It's very, very busy," he says.
EgyptAir says it does not have confirmation that debris has been found off the coast of Crete.
UK Foreign Secretary Philip Hammond says it is "too early" to speculate on why an EgyptAir plane crashed into the Mediterranean Sea.
Read MoreRelatives of those on board the missing EgyptAir flight have gathered at Cairo's airport in an attempt to get information. But some have complained about the lack of news:
"There is no information at all. No one has any information at all," Mohamed Ramez said.
A brother of a passenger, also at the airport, said: "We just found out from the media that they found the wreckage... I hope they find someone we can pray over."
The BBC's Paris correspondent Lucy Williamson, who is at Charles de Gaulle airport, spoke to an official from the Chadian embassy.
The official had arrived at the airport looking for information about a Chadian student on board the plane.
"He had just lost his mother," he told our correspondent, "and was on his way to Chad to mourn with his family."
It is still unclear what happened to EgyptAir flight MS804, but the news is likely to impact Egypt's tourism industry, the BBC's Sally Nabil in Cairo says.
She adds tourism, a lifeline to the country's economy, has had significant losses since the downing of the Russian jet over the Sinai in October.
Fearing the possibility of further damage to the country's image abroad, officials have been cautious in giving out information about the missing plane, she says.

Egypt's Civil Aviation Ministry "so far cannot confirm that the wreckage of the missing EgyptAir plane has been found", state-run Nile News TV has reported.
What this graphic doesn't show is the sudden descent of more than 25,000ft (7,620m) that Greek Defence Minister Panos Kammenos says took place before contact was lost with MS804.
