A coroner has warned that more deaths could occur unless action is taken following the tragic deaths of 30 British victims in the Tunisia terror attacks.

Thirty-eight people were killed by Seifeddine Rezgui on June 26, 2015, at the five-star Riu Imperial Marhaba Hotel in Sousse.

Among the victims was 52-year-old Stuart Cullen of Lowestoft, who was on holiday with his wife Christine.

Judge Nicholas Loraine-Smith concluded the inquests into the deaths of the British tourists in February this year, but in a report published today said organisations still needed to take action to prevent future deaths.

The report said: 'I heard evidence that prior to the attack neither TUI nor other travel companies had security advisors on their boards. The evidence of a TUI witness was that 'security was a matter for the accommodation hoteliers and providers'. I am informed that TUI now have such an advisor. However I remain concerned that if other companies do not have similar security advisors at board level then hotels which they use will not be adequately protected.'

He also said that evidence heard prior to the attack said that TUI's websites for Thomson and First Choice did not prominently display logos and links to the Government's Travel Aware programme, which provides detailed travel advice for every country on the Foreign and Commonwealth Office website.

He said: 'I heard evidence that TUI have taken steps to change their website and promotional literature to make these logos and links more prominent. I remain concerned that other companies which sell holidays, or sell flights and hotel accommodation separately, may not have taken such steps, as a result of which members of the public receive insufficient information about the risks of terrorist attacks in destination countries.'

The report has been sent to the Secretary of State for Transport, the Secretary of State for Foreign and Commonwealth Affairs, the chief executive of ABTA and the chairman of the Civil Aviation Authority.

The inquests concluded that the victims were killed by a terrorist armed with a firearm and improvised explosive devices.

Each victim sustained the fatal injuries in the hotel grounds, inside the hotel or on the hotel's beach.
