A Japanese climber and his Sherpa guide were swept away by an avalanche in the Himalayas but another Japanese climber survived the ordeal, the Ministry of Tourism said Monday.

The ministry said the three - Akihiko Mori and Tsuyoshi Ono, both 43, and their guide Ang Dawa, 27 - were descending after depositing food and tents at the 19,350-foot level of Annapurna when the avalanche roared down the northwest ridge of the 25,545-foot peak at 7:15 p.m. Thursday. The three climbers were only 30 minutes from reaching their first camp when Mori and Dawa were swept away, the ministry said. Ono escaped.
