Two Spanish climbers rescued from the world's second-highest peak confirmed that Scottish climber Alison Hargreaves was among those killed when an avalanche struck the mountain. The Spaniards reported by telephone to a colleague that they had seen the woman's body on K2 in the Himalayas. They identified it from clothing and climbing gear. It was still unclear how many climbers died when an avalanche and bad weather struck the mountain last Sunday. American Rob Slater and Bruce Grant of New Zealand are still missing, U.S. officials in Islamabad said. In May, Hargreaves, 33, became the first woman to reach the top of Mt. Everest alone without using oxygen.
