(KATHMANDU, Nepal)—An avalanche triggered by a massive earthquake in Nepal smashed into a base camp at the foothills of Mount Everest on Saturday, killing at least eight climbers and guides, injuring many and leaving an unknown number missing near the mountain’s most dangerous spot, officials said. The avalanche struck between the Khumbu Icefall, a notoriously treacherous rugged area of collapsed ice and snow, and the base camp where most climbing expeditions are, said Ang Tshering of the Nepal Mountaineering Association. An official with Nepal’s mountaineering department, Gyanendra Shretha, said the bodies of eight people had been recovered and an unknown number remain missing or injured.
