Travel giant Thomas Cook has pulled out all 1,800 of its customers currently on holiday in Tunisia because of security concerns. Whilst thousands of protestors call for President Zine al-Abidine Ben Ali to quit immediately, the tour operator has cancelled all its scheduled departures for the North African country on Sunday 16 January. Thomson First Choice is also planning to cancel its departures. The UK, the US and France are now among the countries advising against non-essential travel to Tunisia. “Those tourists who are currently in the country should continue to remain vigilant, and follow advice from their tour operator and the Foreign Office,” read a statement from ABTA. There have been no reports of British nationals being affected by the unrest and foreigners are unlikely to be targeted.” ABTA has estimated that there are currently around 5,000 British tourists in the country in a number of different resorts, including Sousse, Portel Kantoui, Hammamet, Djerba, Skanes and Mahdia.
