The fifth Briton known to have died in the Sharm al-Sheikh bombings in Egypt last month has been named by his family as 17-year-old Matthew Fulham.
Matthew had returned to the hotel shortly before the explosions
He died in the Ghazala Gardens Hotel blast one day before his 18th birthday.
The family, six of whom were holidaying there, had thought he was safe but later discovered he had returned to the hotel shortly before the explosions.
Another five UK citizens are missing and feared dead after three explosions on 23 July, which killed nearly 70.
A mother and daughter from Essex and a 29-year-old man from Hampshire are among those British tourists confirmed dead.
The Foreign Office is not confirming any details of the dead and missing until the UK coroner has released their identities.
Valerie Bracci, 70, of Canvey Island, Essex, and her daughter Lesley Ayers, 50, of Basildon, were also killed at the Ghazala Gardens, which was destroyed by a car bomb.
Also confirmed dead are Keri Davies, 29, from Fareham, Hampshire, and his American girlfriend Kristina Miller, 26.
One other Briton is known to have died but has not yet been named.
Matthew Fulham's family are waiting to return his body to the UK.
In a statement released through the Foreign Office, they said: "Five members of the family were in their rooms at the time of the explosion, and are safe and well.
"The sixth member, our son Matthew, 17, was thought to be in the town of Naarma Bay.
"However, we have since found that he returned to the hotel shortly before the explosion with a group of friends he had made at the hotel.
"We were due to celebrate his 18th birthday on 24 July.
"Sadly, it has been confirmed that Matthew was amongst those who died," they said.
The family thanked those people who had helped in Egypt and at home, and the UK police.
