Nepalese mountaineering officials say they are investigating reports of a fight between three foreign climbers and local Sherpa guides on Mount Everest, the Associated Press reports.
Dipendra Poudel of the Mountaineering Department said the three climbers - from Italy, Switzerland and Britain - were involved in arguments with the guides on Sunday.
Poudel said that both sides are accusing each other of starting the fight, adding mountaineering officials based at the Everest base camp were investigating the incident.
Sherpa guides hired by the hundreds of Western climbers attempting to climb Everest are the first ones to fix the ropes on the routes so their clients can climb to the peak.
The Sherpas are accusing the foreign climbers of starting the fight.
