FILE: Images of the attack in a hotel in Sousse, Tunisia A US air strike targeting an Islamic State training camp in Libya "likely" killed an IS operative, Noureddine Chouchane, linked to two major jihadist attacks in Tunisia last year, a US defense official said Friday. Chouchane is suspected of being behind two IS-claimed assaults. The first, in March, saw an attack on the National Bardo Museum in Tunis that killed 21 tourists and a policeman. In July, an attack on a beach resort near the Tunisian city of Sousse killed 38 tourists -- including 30 Britons. FILE IMAGES of the attack on a hotel in Sousse in Tunisia on June 26, 2015
