A Sherpa girl around 15 years old may have broken the record for the youngest successful climber of Mount Everest , a Nepal Mountaineering Association official said. Ming Kipa Sherpa reached the world's highest summit Thursday as part of a Romanian expedition.

　　The mountaineering official said Ming Kipa Sherpa was around 15 but did not immediately know her exact date of birth to verify whether she had broken the record.

　　Lhakpa Sherpa, Ming Kipa Sherpa's sister, who reached the world's highest summit along with Ming Kipa Sherpa, also broke a record with the expedition by becoming the first woman to conquer Everest three times. She successfully climbed the 8,848-meter mountain in 2000 and 2001.
