Two Mongolian climbers are going missing above 8,000m on Everest in the middle of summit waves. They were climbing without supplementary oxygen or sherpa support.

Usukhjargal Tsedendamba and Prevsuren Lkhagvajav last made radio contact with Base Camp as they left Camp 4 at 7:30 pm on Sunday. They planned to reach the summit the following morning but never contacted Base Camp again. The climbers, outfitted by 8K Expeditions, had hired only Base Camp services and some bottles of O2 that they did not intend to use.

Searching team has started searching operation and five people from missing climbers’ family arrived in Nepal.

This morning, rescuers have recovered a body of climber Ts.Usukhjargal near the south summit of Mt Everest while another fellow climber has still gone missing, expedition organisers said.
