All 30 Britons killed in the Tunisian beach attack have been identified, Foreign Secretary Philip Hammond has said.
It came as the bodies of more victims were flown back to Britain, nearly a week after Seifeddine Rezgui opened fire in the resort of Sousse.
Tunisian authorities have arrested a number of people suspected of having links to the massacre.
David Cameron has vowed "we will prevail" in the struggle against extremism, in the wake of the terror attacks in Tunisia and Kuwait.
Addressing the Commons, he said there was no evidence the attacks - for which Islamic State, also know as Isil, has claimed responsibility - were "directly co-ordinated".
But as he outlined a series of plans at home and abroad to confront extremists targeting the UK, he told MPs:
"This is not the war between Islam and the West which Isil want people to believe - it is a generational struggle between a minority of extremists who want hatred to flourish and the rest of us who want freedom to prosper - together we will prevail."
Stories continue to emerge of the heroism and compassion of Tunisians who tried to help in the wake of the Sousse attack.
Seifeddine Rezgui was halfway through a Masters degree and took exams at the Institute for Applied Science and Technology before the attack.
As details of the dead continue to surface, James Jordan met Mohamed Sabhi, who ran towards the carnage to shepherd tourists to safety.
