Once again, climbers are going missing above 8,000m on Everest in the middle of summit waves. Two Mongolian climbers disappeared after leaving Camp 4 for the summit. 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 yesterday, but they could not find any clue about the missing climbers yet. Today, the search was suspended due to bad weather, but has been resumed. According to the source the searching team is almost approaching 8,600m. And five people from missing climbers’ family arrived in Nepal.
