An injured British man wearing military fatigues has been captured by Russian forces in Ukraine and paraded on television.
Named as Andrew Hill, he was filmed with a bandaged left arm and a makeshift bandage around his head.
Sky News understands he is 35-years-old.
He was filmed while being questioned, saying he had travelled to Ukraine of his own accord to help the country, Reuters reported.
Mr Hill signalled a connection with the International Legion, a unit set up by the Ukrainian government for foreigners who want to fight in support of the war effort
Asked by his questioners about his rank, the Briton said: "I don't have a rank... I just know the foreign legion said I could help."
Russia's defence ministry said he had surrendered to Russian troops in the Mykolaiv region of southwestern Ukraine.
It is the same region where a second British man, Scott Sibley, 36, a former soldier, was killed a few days ago.
During filming, Mr Hill said he was from Plymouth and had four children and a partner.
Russian soldiers took his passport, he added.
Two other British men have also been detained by Russian forces in Ukraine.
Aiden Aslin, 28, and Shaun Pinner, 48, were captured earlier this month while defending the southeastern city of Mariupol.
On Thursday it was revealed a British army veteran had been killed after he was believed to have travelled to Ukraine to fight.
It is not clear on what day Scott Sibley, 36, was killed but it is thought to have been a few days ago in southern or eastern Ukraine.
Mr Sibley's family has been informed about the situation and is being supported by the Foreign Office.
Meanwhile, two British aid workers have reportedly been captured by Russian forces.
UK non-profit organisation Presidium Network said Paul Urey, 45, and Dylan Healy, 22, were captured on Monday.
They are understood to have been seized at a checkpoint south of the city of Zaporizhzhia in southeastern Ukraine.
