Seven men and a woman remain in custody suspected of being directly linked to Friday’s gun attack on holidaymakers in the Tunisian resort of Sousse.
Four others who had earlier been detained have now been released.
Security forces are still hunting for two men suspected of having trained in Libya with the 28-year-old Tunisian student, Seifeddine Rezgui, who opened fire on a beach killing 38 people including 30 British holidaymakers.
They have released photos of two suspects – Bin Abdallah and Rafkhe Talari – both friends of Rezgui.
According to the Tunisian authorities, the Sousse attack was linked to the shootings at the Bardo museum in Tunisia’s capital, Tunis, in March, with the attackers all having trained in the same group in Libya.
All of the British people killed in Friday’s attack were British customers of Thomson and First Choice.
RAF repatriation flights continue to bring the bodies of the victims back to Britain.
Friday marks a week since the attack, and a minute’s remembrance will be held at noon across the UK as well as in British embassies and posts around the world.
