A British army captain, who is from Dublin, was found dead in the Brecon Beacons in Wales.
Police are investigating the sudden death of Captain Rob Carnegie, whose body was found at Corn Du, Storey Arms, in the Welsh mountain range.
A Dyfed Powys Police spokeswoman confirmed that Captain Carnegie's death was reported at 9.42pm on Saturday.
Captain Carnegie was a member of the Royal Signals.
"We are devastated by the loss of Rob who was a loving son, brother and uncle," his family said in a brief statement issued by the British Ministry of Defence.
"He died doing the job he loved as an officer in the British army."
An army spokesman said: "It is with great sadness that we can confirm that Captain 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."
