The family of a British climber who died shielding his wife from falling rocks at Yosemite National Park have described him as "our hero" who was killed in a "last act of love".

Andrew Foster, 32, was trapped when more than 1,000 tonnes of rock fell from the face of the El Capitan monolith on September 27.

He was seen running back to the rockfall to protect his wife, Lucy Foster, 28, and dived on top of her - saving her life.

The pair were returning from a climb when a sheet of granite around 131ft (40m) by 66ft (20m) plummeted from a height of 656ft (200m).

Mrs Foster is now in a stable condition in a hospital in California and is awaiting clearance to return to the UK, where she lives in Cardiff.
