Avalanche 'deadliest day' in K2 history
Updated
An avalanche near the summit of the world's second highest mountain, K2, in northern Pakistan, has left at least nine people dead.
Expedition organisers say five members of a South Korean climing group died on their way down from making the ascent, after a chunk of ice broke through fixed lines along a dangerous gully known as the Bottleneck.
Several other teams were on the mountain at the time, and officials say those known to have been killed include three South Koreans, two Nepalese, and climbers from Serbia, Norway, Holland and France.
More climbers remain unaccounted for, in what's believed to be the deadliest day in the mountain's history.
