A 47-year-old Nepalese Sherpa on Saturday scripted history by becoming the third climber to scale Mount Everest for a record 21 times.
Kami Rita Sherpa stood atop the 8,848 metre peak, the world's highest, at 8:15 am.
Jiban Ghimire, Managing Director at Shangri-La Nepal Trek, said that Kami Rita climbed the peak as part of the Alpine Ascents Everest Expedition.
He became one of the three climbers in the world to hold the record for most of the summits on Mt Everest, Ang Tshering Sherpa, president of Nepal Mountaineering Association, said.
Earlier, Apa Sherpa and Phurba Tashi Sherpa have scaled the highest peak 21 times.
Since Edmund Hillary and Tenzing Norgay first summitted Mount Everest in 1953, the peak has become both the pinnacle of any high-altitude climber's career.
The final day of ascent goes over three prominent rocky steps on the north-east ridge at an altitude of more than 8,500m (27,887ft) in the so-called "death zone".
Ten fatalities occured on the world's tallest peak this season.
Nearly 300 people have died on Mt Everest since the first ascent to the peak was made in 1953. It is estimated that more than 200 dead bodies are still lying on the mountain.
Nepal has cleared 371 mountaineers to climb Mt Everest during the current season ending this month.
