Scottish mountaineer Rick Allen has died in an avalanche on K2 as he attempted to take a new route to the summit.

The Aberdeen-born climber was climbing the world's second-highest mountain to raise money for the Partners Relief And Development charity.

But the 68-year-old was killed when he was caught in an avalanche on the mountain's south-east face.

His two climbing partners, Jordi Tosas of Spain and Stephan Keck of Austria, were rescued without major injuries.

Mr Allen had previously been presumed dead in 2018 after falling from an ice cliff during a solo climb to the summit of Pakistan's Broad Peak that, at 8,047m, is the 12th highest mountain on Earth.

However, his rucksack was eventually spotted by a cook at the mountain's base camp before a drone was used to locate him and to guide rescuers to his location.

Announcing Mr Allen's death today, Partners Relief And Development, said he was attempting a new route on K2.

In a statement they said: "Rick, a world-renowned veteran mountaineer, was caught in an avalanche on the south-east face but fortunately his two climbing partners survived.

"Rick died doing what he loved the most and lived his life with the courage of his convictions.

"Rick was committed to serving the world's poorest and most vulnerable communities, and worked as a key member of the leadership of Partners Relief And Development UK for several years, campaigning for free, full lives for children affected by conflict and oppression.

"All members of the board send our condolences to Rick's family."

A Foreign Office spokeswoman added: "The British High Commission in Islamabad is aware of reports that a British citizen has died climbing K2 and stands ready to assist."

On the fundraising page shared by the international aid charity, the description read: "Two of Britain's most experienced mountaineers, Rick Allen and Jerry Gore, are attempting the ascent of K2, the second highest peak in the world and the most challenging.

"If the pair are successful, Jerry will be the first British and the first French mountaineer with type 1 diabetes to reach the summit of K2."

The fundraising effort had received just over £1,000 of the £10,000 target at the time of writing.
