One of two men who died after being struck by lightning in Wales may have been hit because he was carrying a selfie stick.

The man was walking with the metal pole, which may have attracted the lightning, when the electrical storm stuck the Brecon Beacons mountain range in Powys on Sunday, UK newspaper The Telegraph reports.

The other man who died was not part of the same party, with the lightning strikes taking place in separate incidents, rescuers said.

Two other men were also injured due to lightning strikes in the same storm.

Royal Marines cadet instructor, James Nunn, was training in the beacons when the storm struck and told the BBC the scene was “like something out of a movie”.

"As we were climbing up we heard the lightning strike the top of the mountain," he said.

"I saw the flash but not the bolt. We kept going to get to the top.”

At the top, Mr Nunn said he saw a female colleague of one of the victims trying desperately to resuscitate him.

"We rushed over and helped out. We carried out resuscitation for around 45 minutes until mountain rescue arrived.

"Just heading up the mountain was pretty intense. It was like something out of a movie. It was a peaceful day at the bottom."

One of the victims, aged in his 50s, was leading children on a Duke of Edinburgh awards scheme, The Telegraph reports.

The man, who was an accredited Duke of Edinburgh awards assessor, had been waiting at the summit for a group of 15 teenagers when the lightning struck.

The group was directed back down the mountain by another leader when the storm broke.
