We are going to bring this live page to a close now.

To wrap up what we know so far:

 - At least 15 Britons have been confirmed dead by the Foreign Office, which warned the toll could rise. 

 - Three of the Britons who died in the attack have been named as Carly Lovett, Adrian Evans and Joel Richards.

 - Foreign Minister Tobias Ellwood has said it was "the most significant terrorist attack on the British people" since 7 July, 2005.

 - Tour companies and airlines have been flying tourists out of Tunisia and home to the UK.

Jet2.com and Jet2holidays will now be cancelling all flights and holidays to Tunisia up to and including 5 July 2015. 

Jet2holidays customers will be offered a full refund or the option to change their booking without an amendment fee. Jet2.com customers will be given a full refund. 

In the meantime, those people in a resort wishing to return home are already transferring to the airport in Enfhida and are boarding aircraft home to Leeds Bradford and Manchester Airports.

Customers are also being urged to check the Jet2.com and Jet2holidays' websites and social media channels for immediate information.

Two relatives of Tunisian gunman Seifeddine Rezgui have been 'horrified' by news of the killings on Friday.

An uncle and a cousin told the BBC that they had seen him literally two or three days before the event and that there was nothing in his behaviour to indicate he had been radicalised or that he was about to carry out an attack.  

His parents and sister and all of his close friends have been detained for questioning.

The family of Denis and Elaine Thwaites from Blackpool have been told the couple are alive but injured and in a Tunisian hospital.

According to the Thwaites' son-in-law the news came via a friend who is in Tunisia who had been told by Thomson representatives. 

He does not know any more about the condition of the retired couple. 

Senior Scottish politicians have been taking part in a Scottish government resilience meeting (SGORR), along with officials and senior representatives from Police Scotland, to discuss the ongoing response to the situation in Tunisia. 

Speaking after the meeting, First Minister Nicola Sturgeon said: "This has been a horrifying and senseless act of violence.

"Our heartfelt condolences go to all of those who have lost loved ones in this horrific attack. My thoughts are also with any families who are worried about relatives they may not have been able to contact and with all those who have sustained injuries.

Foreign Minister Tobias Ellwood has also said that as well as the 15 Britons who are now known to have died "several more people were severely injured".

This is a picture of Dougie Lamb who has been missing in Tunisia since the attack. The baby is his grandchild, and the photo has been sent in by his step-daughter Carol Mulhall.

Fifteen Britons have died in Friday's Tunisian attack and the death toll "may well rise", Foreign Minister Tobias Ellwood has said.

He added it was "the most significant terrorist attack on the British people" since 7 July, 2005.

Jet2 customers in Tunisia told the BBC earlier they felt abandoned by the company and had not received any support. 

Steve Lee, the commercial director for Jet2, has since told the BBC it had been difficult to contact customers.

He said: "The mobile networks were jammed, we were trying to get through to customers who had either left their telephones on beaches or wherever else that they'd left at the time that the incident started. 

"But we've been working through last night, through today... as we speak we've got around 230 customers on transfer coaches to the airport."

There are "grave concerns" about two more Irish citizens who were at the scene of the Tunisian beach massacre, Ireland's Foreign Affairs Minister has said. 

Charlie Flanagan said authorities are in contact with the families of the two citizens who are still missing.

An Irish mother of two, Lorna Carty, from Robinstown, Co Meath, has already been confirmed as among the dead. 

Steve White, from Cramlington in Northumberland, is concerned about his wife and daughter who are currently trying to get home from the resort.

He told the BBC: "I appreciate it will be hectic for tour operators in Tunis but I'm flabbergasted as I understand that it appears that all German holidaymakers were repatriated to Germany by 9pm last night, yet the UK-based holidaymakers are still not sure when they will return."

The airline EasyJet is to provide an extra flight from Monastir to Stansted today for tourists that want to come home.

It said it was contacting all of its customers in Tunisia about this flight, though customers can also contact easyJet on 0330 365 5000 to be booked on it. 

The flight is due to depart Monastir at 17.45 local time.

I'm standing now in the village of Jaafour, and this is where where the man who is widely alleged to have carried out the attack down on the beach at Sousse, was born and bred. 

He lived here until he was 19 or 20 and then he went off to university at Kairouan but he continued to come and go from the village. We've talked to some of his family...they were very, very shocked by what happened...

It seems that just the day before, on Thursday, he was in the village here and he had his beard shaved off. 

But everybody we have talked to here in the village... they all said he was just a very normal guy... he prayed like other people here, he fasted like other people here, but he showed no signs at all of extremism. 

So the tendency here in the village is to blame Kairouan or perhaps radical elements at mosques or wherever in Kairouan itself...

Adrian Evans - who was an employee of Sandwell Council in the West Midlands - has been confirmed locally as one of the dead from Tunisia. 

Adrian's nephew Joel Richards, aged 22, a local football referee, is also among the dead, according to reports.

Tourists John Welch, 74, of Corsham, Wiltshire, and his partner Eileen Swannack, 70, have not been in contact with their family since the attack, and concern is growing for their welfare (see earlier entry at 15:24). 

Now the grandson of Mr Welch has also been in contact with media outlets and said he is preparing himself for the worst.

Daniel Welch, 29, of Swindon said: "You know that we're going to get some sort of news at some point, whether it be today, tomorrow or the next day, and you know it's probably not going to be great, because they haven't been able to make contact themselves by now. 

"But it's just that not knowing."

A piece in the Lincolnshire Echo, external has reported some more details about Carly Lovett. The paper says she was 24 years old and worked as a photographer.

David Schofield and Nicole Harris have told the BBC how relieved they feel to be back home in Maidstone after being caught up in the attack.

"We're incredibly lucky that we are here in the UK and that obviously we weren't on the beach at the time," David said. 

"We came down to the lobby at around 10.00 last night and were told that if we could pack in half an hour, those who wanted to can get on a flight.

"We landed into Gatwick around 6.55 this morning and managed to speak to everyone we wanted to.

"We really do feel very, very lucky to be back and safe - and thank the people who organised that."

Nicole said: "I remember saying to David to make sure we stayed away from the windows and the doors and to get ourselves up to our room and to stay safe.

"I don’t think we would be going back to Tunisia any time soon. We made the decision quite quickly to come home and we are thinking more about the friends and family of those who are not coming home."
