Three mountain climbers are feared dead after an avalanche at a Canadian national park.

The climbers, part of the North Face Global Athlete team, include American Jess Roskelley and Austrians David Lama and Hansjorg Auer.

They set out to scale Howse Peak at Banff National Park but never returned.

Signs of “multiple avalanches”, along with “debris containing climbing equipment” were found by a search team sent out.
