ZURICH, Aug 9 (Reuters) - Two American climbers have been found dead on the Matterhorn mountain in the southern Swiss canton Valais, local police said on Saturday. The bodies of the 57-year-old woman and the 53-year-old man were found at an altitude of around 4,000 metres late on Friday, said Jean-Marie Bornet, head of information and prevention for the Valais cantonal police. The two climbers had been missing since Thursday. "They were climbing, then they fell and were killed. It is not clear why they fell," but the weather was bad at the time, Bornet said. He did not give the climbers' names or home town. (Reporting by Katie Reid, editing by Tim Pearce)
