Five South Korean climbers and four Nepalese guides were missing on Gurja Himal mountain after a strong storm swept through their base camp, officials and expedition organizers said.
A storm today destroyed their camp and rescue helicopter sent today were unable to land because of bad weather conditions on the mountain, police official Bir Bahadur Budamagar said.
It was unlikely the weather would clear today and the base camp is at least one-day trek from the nearest village.
A police team was also heading toward the base camp on foot and would likely reach there overnight.
The climbers were attempting to scale the 7,193-metre peak during the Autumn climbing season.
