Among those waiting for news is Ross Naylor, whose father Scott Chalkley, 42, was staying at the Imperial Hotel with partner Sue Davey. 

Mr Naylor said he has not heard any news on their whereabouts despite several calls to their mobile phones, the hotel, the Foreign Office and a local hospital. 

Mr Naylor, of Derby, added his fears had increased after hotel staff told him his father and partner were on the beach and had found some of their bags on the sand. 

Ms Davey's son Conor Fulford, from Tamworth in Staffordshire, earlier said she was missing but he thought he had seen her on a stretcher during a television report.

Eyewitness Katerina has told BBC correspondent Ben Brown of her experience during the attack.

The German tourist said: "The security told us to run, go into your rooms, run away.

"It was like in war. I really was afraid. I don't know why they are doing this." 

Jet 2 has said it will fly any customers who want to return to the UK home today. Planes will be arriving in Tunisia this afternoon. 

Acting Labour leader Harriet Harman has responded to events in Tunisia.

Assistant commissioner Mark Rowley, national policing lead for counter-terrorism, says it is "fairly clear" the location of the Tunisian attack was chosen because of the number of Westerners present in the area.

Scotland Yard has said police travelled to Tunisia to help investigate the killings and officers are also interviewing tourists returning at British airports.

Sean Tipton, from the Association of British Travel Agents, tells the BBC: "I think it is really that a tour operator should contact its customers to let them know what's going on.

The Tunisian health ministry is reporting at least eight of the victims of the attack were British.

A German and Belgian have also been identified, it said. 

The Foreign Office earlier confirmed that five Britons had been killed, but this number is expected to rise.

The Scottish government has issued a statement on Tunisia:

The Foreign Office helpline number is 0207 008 0000.

Norfolk Police have confirmed a member of support staff was injured during yesterday's attack. Tony Callaghan was in the country with his wife. Both required hospital treatment, but their injuries are not life-threatening, the force said. 

The Welsh tourist who was shot three times during the attack is due to be flown home, BBC Wales understands.

Matthew James, 30, from Trehafod, near Pontypridd, used his body as a human shield while trying to protect his fiancee when the gunmen opened fire.

Speaking from the hospital on Friday where Mr James, known as Sas, is being treated, fiancee Saera Wilson said: "He took a bullet for me. I owe him my life because he threw himself in front of me when the shooting started.

British tourist Lindsay Nelson, who is staying in the area where the attacks took place, says she and other British tourists have been left without support. 

She tells BBC News the group has had "literally no support" from operator Jet 2. 

Some of those waiting to travel back to the UK witnessed the attack and are "devastated", Ms Nelson says. 

Earlier,  Jet 2 spokesperson told the BBC it would put on extra flights. 

British couple Olivia Leathley and Mike Jones, who survived the attacks on Friday, told the BBC a gunman was "killed about 400 yards" from where they were hiding.
