Thank you for following our live coverage of the Sharm el-Sheikh travel situation.
We will continue to update our main news story so you can keep up to date with it here.
Now for a brief summary before we wrap up our live page.
The UK has halted all flights to and from Sharm el-Sheikh in Egypt - saying intelligence suggests it is "more likely than not" that a bomb caused a Russian passenger jet to crash on Saturday.
Among today's events:
Mr Cameron is also questioned about terrorism.
He says: "I would argue that the problem of extremist Islamism and violence, it's been a growing problem and it's a problem which is effectively a battle that is taking place within Islam."
Mr Cameron says he thinks the UK and Egypt will be able "over time" to take action to restore the holiday-making route from Britain to Sharm el-Sheikh.
Mr Cameron says there have been "excellent discussions" about further steps that can be taken in Egypt to help ensure British tourists can return home.
Asked why the UK decided to cancel flights when others did not, he says the US and some European countries acted in a similar way. He says he acted on advice he received to keep British citizens "safe and secure".
His experts can not be sure it was a terrorist bomb that brought down the plane. But he adds:

Egypt's president says he shares Mr Cameron's concern about safety and his country "responded immediately".
He adds Egypt is "completely ready" to cooperate with all its friends to deliver security improvements.
He says he has spoken with David Cameron about the "actions needed to make sure this will not have any negative ramifications" on tourism in Egypt.
President Sisi is asked about the UK's decision to cancel flights to Sharm el-Sheikh.
He says Egypt was asked 10 months ago by the UK to send teams to check security at the airport.
Egyptian authorities cooperated and the UK was "happy with that", he says.
He adds Egypt is "ready to cooperate, not necessarily on one airport but with all airports".
The PM and him agree there should be more coordination on checking security procedures.
Egypt's president says he is confident the countries' bilateral co-operation will prove "mutually beneficial".
President Sisi says the world needs to unify "against the ideas and rhetoric of bigotry, extremism, hate and denial of the other".
Prime Minister David Cameron and Egypt's president Abdel Fattah el-Sisi have begun a joint press conference discussing the situation in Sharm el-Sheikh.
Mr Cameron said the pair were "committed to work together" to meet security concerns at the airport.
British holidaymakers want to go to Sharm el-Sheikh and Egyptians want to welcome them, Mr Cameron said.
“It’s in our mutual interest to address this and get back to normal,” he added.
The airline Monarch is to operate three "rescue flights" and two scheduled flights from Sharm el-Sheikh to the UK tomorrow.
The company said it has 3,000 customers in the resort. All Monarch flights from the UK to Sharm el-Sheikh up to November 12 have been cancelled.
Russian President Vladimir Putin and UK Prime Minister David Cameron have discussed the investigation into the crash of a Russian passenger plane over Egypt at the weekend.
The Kremlin said that Mr Putin had told the PM how important it was that assessments of the possible causes of the crash be based on information from the official investigation.
The comments from Russia come after Mr Cameron said it was increasingly likely a "terrorist bomb" caused a Russian passenger jet to crash on Saturday, killing all 224 people on board on Saturday.
British tourists have clashed with Sharm el-Sheikh hotel staff as tensions rise over delayed flights at the Egyptian resort, the Press Association news agency reports.
It quotes holidaymaker Emma Smyth, who has been staying about 12 miles from the airport in the Aqua Blu hotel, as saying: "One English family, who are obviously upset and concerned, have asked the hotel if they can stay on.
"The hotel have set a charge and the tourists cannot understand why they are being charged.
"They said they should be allowed to stay and with that one man grabbed one of the managers - they ripped his shirt, ripped his name-badge off and everything."
Crowds of people have gathered in Westminster in central London to protest against the visit of Egypt's president Abdel Fattah el-Sisi, who has met Prime Minister David Cameron at 10 Downing Street.
The demonstrators have been protesting against Egypt's record on human rights.
One of the people who will no longer be flying to Sharm el-Sheikh is Andy Massey, from Wakefield in West Yorkshire, who decided to cancel his holiday to a resort there. He had been due to fly with his wife and child on 28 November, but decided to cancel, "even if I lose my money".
He said:
Quote MessageI don't think the security is good enough in the airport. I have been twice before and they have let us through with bottles of water that I didn't realise were in our hand baggage at the time. I have heard that airport staff are not put through the same security checks as EU airports which is a real worry. For the government to take this urgent stance, there is a serious security risk. I just hope that all the Brits get home safe."
Germany's Lufthansa Group has said its Eurowings and Edelweiss carriers have also halted flights to Sharm el-Sheikh, the AFP news agency reports.
We are now hearing that Prime Minister David Cameron and President Abdul Fattah al-Sisi are expected to make short statements later. They are currently meeting inside Number 10.

Norman Shanks, former head of security for the British Airports Authority, tells the BBC Radio 4's World at One it is not unusual for UK experts to carry out checks at foreign airports.
Quote MessageWhat is unusual here is the connection between sending a team out rapidly and cancelling the flights. So that indicates the government has serious concerns about something on the airport operation itself and these people would then be looking at all of the security aspects relating to UK aircraft in particular.
First Minister Nicola Sturgeon holds meeting
There are "at least several hundred" Scottish holidaymakers in Sharm el-Sheikh, First Minister Nicola Sturgeon has said. She has chaired an emergency meeting to discuss the situation. The SNP leader said her officials were in "close contact with UK Government officials and will continue to be so".
The Downing Street spokeswoman said the government "can't be categorical about a bomb", but officials are "increasingly concerned" it may have been the cause of the crash. The UK's national security adviser has spoken to his Russian opposite number. BBC correspondent Iain Watson said Number 10 wouldn't be drawn on who might be responsible for an attack, but admitted the involvement of so-called Islamic State was "a possibility".
