Reports of a fight between Sherpa guides and three climbers on Mount Everest are being investigated.
Anish Gupta of Cho-Oyu Trekking, the Kathmandu-based company that organised the expedition said: "We were told our clients and the guides fought on their way to camp three. We don't have all the details yet, but our clients have come down off the peak."
He added that one of the clients, a Swiss national, had descended the mountain and was currently waiting for a flight back to Kathmandu.
