A plane repatriating some of the British victims of the Tunisia beach attack comes in to land at the RAF (Royal Air Force) Brize Norton base in Brize Norton, England, Wednesday, July 1, 2015. Britain on Wednesday began repatriating the remains of victims of last week's terror attack at a Tunisian beach resort.

LONDON — The bodies of eight British tourists killed in last week's massacre on a Tunisian beach were flown back home Wednesday. A military plane delivered their coffins to waiting hearses in a solemn ceremony marking one of the worst terror attacks on Britons in recent years.

At least 27 Britons are confirmed among the 38 people shot dead when a Tunisian student opened fire on a beach in the North African nation's central resort of Sousse. The British death toll is expected to rise further.

The dead include three generations in the same family — student Joel Richards, 19, his 49-year-old uncle Adrian Evans, and Richards' grandfather Patrick Evans, 78.

"Their holiday lasted less than 24 hours and their futures and lives ended tragically," Suzanne Richards, who lost her son, brother and father, said in a statement. "We are a very small and normal family, but nothing will ever be normal again."

The Royal Air Force flight repatriated the bodies of six other Britons to the Brize Norton air base northwest of London. The repatriation process is expected to last several days.

Wounded Britons have already been brought back to the U.K. for hospital treatment, including four severely injured victims.

British authorities say last Friday's rampage, claimed by the Islamic State group, was the most significant attack on British people since 52 were killed when extremists targeted London's transport system in July 2005.
