Cancellation : An association which looks after more than 50 cruise operators – including P & O , Thomson and Cunard – said no ships would be calling at the city ‘ in the foreseeable future ’ ( file picture ) Italian operators MSC Cruises and Costa Cruises , used by hundreds of British tourists each year , have already scrapped planned stops to Tunisian ports with immediate effect and said they were ‘ seeking alternative ports ’ . Holiday companies Thomson and First Choice said they had also cancelled voyages to Tunis , while P & O , Princess and Celebrity cruises said they were taking advice from security services . A spokesman for the Cruise Lines International Association said last night : ‘ No CLIA member ships are scheduled to call at Tunis in the foreseeable future . ‘ Cruise lines coordinate closely with national and international authorities when visiting destinations around the globe to help ensure passenger safety. ’ Last year , 425,000 British holidaymakers visited Tunisia and last night there were fears that as many as 6,500 could still be in the country . However a spokesman for Thomson and First Choice said : ‘ Our customers stay in beach destinations , not Tunis , and we can confirm that none of our customers or staff were affected by Wednesday ’ s events. ’ He added that , as a precaution , all excursions to Tunis have been cancelled . Meanwhile a spokesman for travel agent association ABTA said the tourist season was only just getting under way but safety was always a priority . He told Sky News : ‘ Tourist numbers to Tunisia have picked up over the last two years and we have had very healthy bookings for this summer . The season really picks up around mid-April to May . Warning : It comes following a stark warning from the Foreign Office that ‘ further attacks are possible ’ .

ABTA follows FCO advice very closely and safety is always the main concern. ’ Bob Atkinson , a travel expert at TravelSupermarket , added : ‘ Tour operators have a responsibility to ensure the safety of their tour operators . ‘ Consumers who already have holidays booked this year will want to be convinced of the safety – most of them will be staying at beach resorts and the vast bulk would not even go to Tunis on a day trip. ’ The Tunis outrage has tragic echoes of the November 1997 Luxor massacre in Egypt , when gunmen killed 58 foreign holidaymakers including six Britons . Tour operators pulled out of the Egyptian market and it was some time before holidays started again . The CLIA spokesperson continued : ‘ Cruise line security personnel , in addition to ongoing communication with national and international security authorities , enhance the security of cruise ships . ‘ CLIA members maintain rigorous policies and procedures designed to safeguard passengers . ’
