Mount Everest deaths: US climber becomes 11th fatality

Dozens of climbers line up to stand at the summit of Mount Everest.

A US climber has died after descending from Everest, officials said Tuesday, taking this season's toll to 11 including several deaths blamed on overcrowding on the world's highest mountain.

American Christopher John Kulish, 61, had already climbed the 8,848-metre (29,029-feet) peak, and was safely back at a camp below the summit on Monday evening.
