A British climber too weak to descend from Mount Everest died on Saturday, bringing the death toll this season on the world’s tallest mountain to ten.

Hiking officials attributed most of the deaths to weakness, exhaustion and delays on the crowded route to the 8,850-metre (29,035 feet) summit.

Robin Haynes Fisher, 41, died in the so-called ‘death zone’ known for low levels of oxygen on descent from the summit, Mira Acharya, a tourism department official said.

He is the tenth fatality on Everest in the current climbing season that ends this month and the 18th in Nepal’s Himalayas in the same period.

‘He died because of weakness after a long ascent and difficult descent,’ Murari Sharma of the Everest Parivar Treks company that arranged his logistics told Reuters.

‘He was descending with his sherpa guides from the summit when

Fellow guides changed Fisher’s oxygen bottle and offered him water, but could not save him, Sharma said.

Mr Fisher’s death follows the death of an Irish climber in the early hours of Friday.

Kevin Hynes, 56, died in his tent at 7,000 metres after turning back before reaching the summit.

The father-of-two was part of a group from UK-based climbing company 360 Expeditions which was attempting to scale the world’s highest mountain.

And his death comes a week after Trinity College professor Seamus (Shay) Lawless, 39, from Bray, Ireland, fell during his descent from the peak having achieved a lifetime ambition of reaching the summit.

Mr Lawless fell on the 27,000-ft high ‘balcony’ area of the world’s highest mountain and the search for him has since been called off.

An American climber, Austrian climber and two Indian climbers are also reported to have died in the last week.

Garrett Madison of the U.S. based Madison Mountaineering company that sponsors climbers to Mount Everest said many were not ‘well qualified or prepared climbers’ and were without the support necessary to ascend and descend safely.

‘If they were with a strong and experienced team they would have likely been fine, but with minimal support, once something goes wrong it’s tough to get back on course,’ Madison told Reuters.
