LONDON — Britain says militants may launch further attacks on tourist resorts in Tunisia after a gunman killed 39 people, including at least 15 Britons, in the worst assault of its kind in modern Tunisian history. Attacks may be carried out by “individuals who are unknown to the authorities and whose actions are inspired by terrorist groups via social media,” the Foreign Office said in updated travel advice on its website late on Saturday. Britain's Defense Secretary Michael Fallon and Foreign Secretary Philip Hammond, writing in separate Sunday newspapers, said the Tunisian murders would inform Britain's defense and security this year and stiffen London's resolve to tackle what they described as the poisonous narrative of extremism. With some British tourists holidaying in Tunisia still unaccounted for, the number of Britons confirmed killed in the attack is expected to rise. Britain's Foreign Office has updated its travel advice to Tunisia, urging vigilance. The ministry is warning Sunday against all travel to Tunisia's militarized southern zone, all travel anywhere within 5 kilometers (3 miles) of Tunisia's border with Libya and all travel to the country's Chaambi Mountain national park area. It also advised against all but essential travel to much of Tunisia's south and along its western border with Algeria. Tunisia's top security official says 1,000 extra police are being deployed at tourist sites and beaches in the North African nation. Interior Minister Mohamed Najem Gharsalli made the announcement late Saturday. He said "we don't want to make tourist establishments into barracks, that's not our goal. But we must act to guarantee the security of the tourist sector." Thousands of tourists fled Tunisia on Saturday after the country's worst terrorist attack killed 38 people. Hundreds more were to leave Sunday. — Agencies
