Avalanche kills three in Rocky Mountains

An avalanche struck a rally of up to 200 snowmobilers in Canada's Rocky Mountains last night, killing at least three people and leaving an unknown number missing, police said.

Rescuers were still scouring remote Boulder Mountain, near Revelstoke, British Columbia, the Royal Canadian Mounted Police said. The RCMP said a dozen people were injured in the slide but up to 200 people were on the mountain at the time.

Search and rescue teams were called in from around British Columbia and from Calgary.
