瑞士一位登山者在登上珠穆朗玛峰顶之后因过度疲劳死亡。
他的登山同伴说，44岁的詹尼.戈尔茨在没有氧气瓶帮助的情况下攀登上近9千米的高峰。
由于空气稀薄，呼吸困难，不借助额外的氧气而攀登珠穆朗玛峰被认为是危险的。
在此之前不久，有关官员宣布，一位资深的夏尔巴人向导星期四在创下18次登上珠峰峰顶的纪录后死亡。
A Swiss climber has died from exhaustion after making it to the top of Mount Everest.
Fellow climbers say 44-year-old Gianni Goltz had scaled the nearly nine-thousand-meter-high mountain without the aid of bottled oxygen.
Climbing to the top of Mount Everest without additional oxygen is considered risky because of the very thin air, which makes it hard to breath.
News of the death came shortly after officials announced that a veteran Sherpa guide climbed to the top of Mount Everest for a record 18th time Thursday.
