KATHMANDU, Nepal (AP) — An avalanche swept the face of Mt. Everest after the massive earthquake struck Nepal on Saturday, a senior mountaineering guide, injuring at least 30 people.

The avalanche apparently struck between the Khumbu Icefall, a rugged area of collapsed ice and snow, and the base camp where most climbing expeditions are, said Ang Tshering of the Nepal Mountaineering Association.

Tshering said details were unclear because communication between the base camp and the rest of the Everest region was intermittent.

Nepal's Home Ministry said that the 30 people who were injured were at the base camp.
