An amateur Korean mountaineer has gone missing while descending Mount Everest.
The Korean Embassy in Nepal said Sunday that 24-year old Song Won-bin went missing after he fell off a cliff late Saturday night while returning to his base camp.
Song was reportedly suffering from altitude sickness when the accident happened.
The embassy says it is investigating the accident and preparing a search and rescue mission.
Song was among a team of 10 amateur mountaineers that arrived for an expedition of Mount Everest in late March.
The group was planning to return to Korea before the end of the month.
