A man has died after he collapsed while hiking in Snowdonia, emergency services have reported.
The incident occurred on the Cadair Idris mountain in the southern part of Snowdonia National Park, near the town of Dolgellau in Wales.
The Aberdyfi Search and Rescue Team confirmed that a man was taken ill on Tuesday afternoon and tragically died.
Desperate passers-by tried to help the man, providing prolonged CPR, but they were unable to save him.
Despite the best efforts of members of the public, and advanced interventions by a coastguard winchman paramedic, the man, aged in his 60s, could not be resuscitated.
A Coastguard helicopter was involved in rescue efforts and transported him off the mountain, NorthWalesLive reports.
A statement by the Aberdyfi Search and Rescue Team said: "Shortly after 4pm on Tues 23rd May call-handlers from Aberdyfi Search & Rescue Team were made aware of a collapsed walker on Cader Idris.
“A group of six walkers had come across an unresponsive lone male in his sixties beside the Minffordd Path just below Llyn Cau.
"The group called for help and started CPR which they continued for an extended period under the guidance of an ambulance call-handler. This was advised because further medical support was on the way.
"Two team volunteers arrived on foot at about the same time as coastguard helicopter R936 reached the scene. Further team members were also airlifted to support the operation.
"The paramedic winchman was able to administer appropriate advanced medical interventions and CPR continued for a further 30 minutes, but with no response evident the decision was made to cease resuscitation attempts.
“The casualty was flown down off the mountain and placed in the care of waiting police officers while team volunteers and the group of walkers made their way off the mountain."
In February, amateur climber Jack Carne from Barnsley, South Yorkshire, was ascending Y Gribin in Snowdonia National Park died after a handhold gave way.
Jack fell 600ft down the mountainside.
Rescue teams were then called to a valley between the 3,200ft Glyder Fawr and Glyder Fach peaks, with the body of the 23-year-old builder found later in the evening.
Cloudy conditions, regular rockfalls, and widespread ice in the area where he was found meant rescuers were prevented from trying to evacuate him until the following morning.
