A soldier has died on south Wales’s second highest mountain.
Captain Rob Carnegie’s death on Corn Du was being investigated, the Ministry of Defence said.
Dyfed-Powys Police said the incident on the 873m (2,864ft) mountain was reported to them shortly after 9.40pm on Saturday.
Conditions on the mountain were wintry.
Capt Carnegie, from Dublin, was a member of the Royal Corps of Signals.
In a statement released through the Ministry of Defence, his family said: “We are devastated by the loss of Rob who was a loving son, brother and uncle.
“He died doing the job he loved as an officer in the British Army.”
An MoD spokesperson said: “It is with great sadness that we can confirm that Capt Rob Carnegie has died in an incident in the Brecon Beacons.
“The soldier’s family have been informed and are being supported. Our thoughts are with them at this difficult time.
“As is normal in circumstances such as this, the incident is being investigated and it would be inappropriate to comment further.”
The Brecon Beacons are used for military fitness training and testing for UK Special Forces. The Fan Dance entails a double ascent of Corn Du’s neighbouring mountain Pen y Fan. The Long Drag is an endurance march across the Beacons also used in Special Forces training.
