Five Hong Kong tourists were injured when their bus rammed into a hill during a sightseeing trip in Tibet yesterday. The five, all women aged between 40 and 50, suffered fractures and were admitted to a hospital in Lhasa in stable condition. The crash occurred shortly after 1pm when the bus, carrying members of a Goexpo Travel package tour, was returning to Lhasa after visiting the famed Namtso Lake. It was one of two vehicles that took 39 tourists to the lake, 220km north of Lhasa. 'The bus suddenly slammed into a hill,' said Chan Hing-wang, a spokesman for the travel firm. 'The five women suffered broken bones during the crash.' He said the other tourists, who left Hong Kong on July 8, were unhurt and would continue their trip, returning tomorrow as scheduled. 'We have already contacted the injured women's families and they have yet to decide if they will fly to Tibet,' Mr Chan said. He said the women had bought their own insurance, as well as a policy from the company that entitled them to about $100,000 compensation each. Last night the Security Bureau said it had been notified of the accident by the Travel Industry Council. A bureau spokesman said: 'We immediately contacted the travel agency. We also followed up the case with the mainland government via the Hong Kong office in Beijing. So far, they have not asked for our assistance.' The executive director of the council, Joseph Tung Yao-chung, said it would offer support to the travel company if it was needed. Namtso Lake - Heavenly Lake in Tibetan - is the world's highest saltwater lake, at 4,718 metres above sea level, and the second-largest.
