KATMANDU: A mountaineering official in Nepal says climbers have reported seeing another body on Mount Everest, raising the death toll to four for one of the worst days ever on the world's highest mountain.

Nepali mountaineering official Gyanendra Shrestha said on Tuesday that the body of Chinese climber Ha Wenyi was spotted not far from where three other climbers died.

Wenyi and the other victims - German doctor Eberhard Schaaf, Nepal-born Canadian Shriya Shah, and South Korean mountaineer Song Won-bin - died Saturday on their way down from the 8,850-meter (35,035-foot) summit.

Shrestha says a Nepalese Sherpa guide who had been reported missing is safe and has reached the base camp. Shrestha says the guide was separated from his group and did not have communications equipment.
