Three generations of one family are believed to be among those killed in the beach attack in Tunisia.

Joel Richard (22), his uncle, Adrian Evans (49), and his grandfather, Patrick Evans (78), were shot dead when Seifeddine Yacoubi opened fire with a Kalashnikov on tourists on the beach in popular holiday resort Sousse.

Joel's 16-year-old brother, Owen, survived the massacre.

Reports indicate that as many as 23 Britons may have been killed in the attack.

Despite being injured himself and losing three family members, Owen Richards reportedly went to the aid of a wounded woman outside a hotel in El Kantaoui, near Sousse after fleeing the killing.

Owen is believed to have been hit by the same bullet that then killed his uncle, who Owen regarded as a father figure and called "dad".

Dr Ben Amor, who treated Owen, told the Sun.

"He said he turned after the bullet flew past him to see his father fall down with a bullet wound to his head – it was the same bullet."

"Owen said it was terrifying and he ran for his life, turning round to look for other members of his family as he sprinted from the beach.

"Every time he turned he saw more people falling. It was only later he found two other members of his family had been killed."

Tributes paid to family

The men were keen supporters of Walsall Football Club, and a picture of the four outside the club's ground is on the club's official Twitter page.

The club tweeted: "Our thoughts are with Adrian & Joel's family & friends. Those wishing to lay scarves at Stadium from Monday can do so outside Main Reception."

A tribute to the men was also posted on Walsall's official Facebook page.

Tributes flooded in for the three members of the family who lost their lives.

Adrian Evans worked for Sandwell Council in Oldbury, West Midlands.

Council leader Darren Cooper said: "Adrian Evans was a very popular and long-serving employee.

"We are absolutely devastated for Adrian's family, friends and colleagues and our thoughts are with them and all those affected by this tragedy."

University of Worcester students Adrian Evans from Wednesbury was a local football referee.

Birmingham County FA, who said he was an active member of its youth council, said: "A young, talented referee with the world at his feet, he was highly thought of and will be sadly missed. Our thoughts and prayers are with his family and friends at this tragic time."

Owen's mother, Suzanne Richards, is believed to have flown to Tunisia to be with her son, who was injured in the shoulder, and is being comforted in hospital by other Britons caught up in the tragedy.

"She's gone out there to bring Owen home," a neighbour told The Mail on Sunday.

As the number of Britons confirmed dead rises, personal details of the victims are emerging.

Islamic State has claimed responsibility for the attack, which took place during the Muslim holy month of Ramadan.
