Another Irish climber has died on Everest, the second in just over a week.
Kevin Hynes, from Galway, died while attempting to scale the world's highest peak from the Tibetan side early yesterday morning, according to expedition organisers.
"It is with the greatest sadness that we have to confirm that Kevin Hynes, from Galway, Ireland, one of our Everest team members, has passed away," 360 Expeditions said in a statement.
"Kevin (56) was one of the strongest and most experienced climbers on our team and had previously summited Everest South and Lhotse."
It is understood Mr Hynes lived in the UK, and had previously scaled Everest last May.
His death is the second Irish tragedy on the world's highest mountain in eght days.
Father-of-one Seamus Lawless (39), from Bray, Co Wicklow, fell at an altitude of 8,300 metres while descending the mountain on Thursday of last week.
Tragedy struck only hours after Mr Lawless, an assistant professor in artificial intelligence at Trinity College's school of computer science and statistics, reached the summit.
Yesterday, his family announced that the search for him had been called off.
In a statement on GoFundMe, they thanked supporters, who had donated more than €267,000 to help the search effort, but said finding Mr Lawless had "ultimately proved too difficult".
"Based on expert advice, we have decided to call off the search rather than risk endangering any-one's life in the treacherous conditions," the family added.
Mr Hynes had reportedly reached Camp III at 8,300 metres on Wednesday.
"Yesterday, while our summit climbers were heading higher, Kevin started his descent. He was accompanied by experienced guide Dawa Sangee, who himself has summited Everest South twice, Everest North and Makalu twice," the 360 Expedititions statement said.
It is understood Mr Hynes died in his tent at 7,000 metres. He was married with two children.
Efforts were under way to bring his body to base camp.
The mountaineering group Irish Seven Summits posted a tribute on Facebook.
"It is with great sadness that we learn today of the death of Galway native Kevin Hynes on Everest," it said.
"Kev (who lived and worked in UK) was on his second expedition to Everest having reached the summit via the Nepal side last year and was attempting the north side this time.
"I spoke to Kevin as recently as last Friday when the team was preparing for the summit push.
"He was extremely private and understated about his climbing but was a very experienced guy (including Everest and Lhotse and many others).
"Our deepest sympathies to his wife and two children at this terrible time. Thinking also of his expedition team and team-mates (360 Expeditions) at this sad time."
