Swiss climber Ueli Steck has been killed preparing to climb Mount Everest in Nepal.

Known as the “Swiss Machine” by the mountaineering community, the 40-year-old died in an accident while acclimatising for an attempt on Everest without oxygen by a new route.

He had won multiple awards and was known for his rapid ascents.

His body was recovered from the base of Mount Nupste, which shares a common ridge with Everest, after he was spotted by fellow climbers.
