A British man has reportedly been captured by Russian forces while fighting for Ukraine.

In a widely circulated video on Sunday, first posted on Telegram, the man identifies himself as James Scott Rhys Anderson, 22, and says he is a former British army soldier.

He is dressed in combat fatigues and speaks with an English accent while appearing to have his hands tied.

He said to the camera: “I was in the British army before, from 2019 to 2023, 22 Signal Regiment. Just a private. I was a signalman. One Signal Brigade, 22 Signal Regiment, 252 Squadron.”

He said he signed up to fight for Ukraine’s International Legion after losing his job.

“When I left, I got fired from my job, I applied on the International Legion webpage. I had just lost everything. I just lost my job,” he said.

“I see it on the TV,” he added, shaking his head. “It was a stupid idea.”

He described how he had travelled to Ukraine from Britain, saying: “I flew to Krakow, Poland, from London Luton. Bus from there to Medyka in Poland, on the Ukraine border.”

Russian state news agency Tass reported that a military source said a “UK mercenary” had been “taken prisoner in the Kursk area” of Russia.

The UK Foreign Office said it was “supporting the family of a British man following reports of his detention”.

The Ministry of Defence has declined to comment at this stage.
