Swiss climber Ueli Steck was killed Sunday in an accident near Mount Everest, Nepal's tourism department said. The 40-year-old died when he slipped from a slope and fell into a crevasse at around 6,600 meters on Mount Nuptse, expedition organizers said.

Steck is seen during a training climb near the village of Chukung, in the Khumbu region in the Himalayas, in February 2017.

Steck on April 24 in the Himalayas prepares himself for an ascent of Mount Everest.

After climbing the Aiguille Verte, a mountain in the French Alps, Steck prepares to parachute down in December 2016.
