An Indian army mountaineering team found 18 bodies on Mount Everest after a huge earthquake in Nepal unleashed an avalanche on the mountain, according to an army spokesman quoted by Reuters news agency.
Nepal's Tourism Ministry could only confirm 10 deaths, but spokesman Gyanendra Shrestha said that the death toll could rise, and that the avalanche had buried part of the base camp.
Ministry officials estimated that at least 1,000 climbers, including about 400 foreigners, had been at base camp or on Everest when the earthquake struck.
Saturday's 7.9-magnitude quake was the strongest to hit Nepal for 81 years and was known to have killed nearly 900 people in Nepal.
Four men trapped under as much as 10 foot of rubble after the Nepal earthquake were rescued when NASA technology sensed their heartbeats.
One medical worker told ITV News it was like 'entering your worst nightmare' as they tried to help look after the injured.
