Bad weather was hampering a desperate search on Monday for two foreign tourists still missing after a boat travelling between two Indonesian islands sank at the weekend, although 13 more people had been plucked from the water alive, officials said. A small cruise ship carrying 20 foreign tourists and five Indonesian crew sank on Saturday night as it sailed between Lombok and Komodo islands. Indonesian authorities had said as many as 15 of the tourists were missing overnight. However, Sutopo Purwo Nugroho, spokesman for the national disaster management agency, said 13 more people, including eight tourists and all five Indonesian crew, had been rescued in the hours since then.
