A Nepalese mountaineering official says three climbers returning from the summit of Mount Everest have died and two more are missing.

Mountaineering Department official Gyanendra Shrestha said Monday that a German, a Nepal-born Canadian and a Korean died Saturday while descending from the 8,850-meter (29,035-foot) summit.

Shrestha said the weather was favorable on Friday and Saturday morning but a wind storm swept the mountain later on Saturday.

Shrestha, stationed at the base camp of Everest, said he was waiting for details.

German climber 61-year-old doctor Eberhard Schaaf was believed to have suffered high altitude cerebral edema.

The Nepalese-Canadian climber was Shriya Shah, while the Korean mountaineer's name was yet to be confirmed.
