A number of people have been caught up in an avalanche in the Scottish Highlands and three are “possibly unaccounted for”, police said.

A climber from the North who was killed in an avalanche in Scotland had a great zest for life and wanted to make a difference, her former schoolteacher said.

Friends have paid tribute to three young climbers, including a woman from the North, killed in an avalanche who, they said, died doing what they loved.
