Russia's Wagner Group has claimed the body of one of the missing British aid workers in Ukraine has been found.
Christopher Parry, 28, and Andrew Bagshaw, 48, were last seen on Friday leaving Kramatorsk for Soledar.
A spokesperson for the Foreign, Commonwealth and Development Office said: "We are supporting the families of two British men who have gone missing in Ukraine.
"We are aware of recent reports and are in touch with the Ukrainian authorities."
A statement on Telegram from the Russian mercenary group said documents belonging to both Britons had been found on the man's body.
Originally from Cornwall, Mr Parry had been working as a running coach in Cheltenham when Russia invaded on 24 February last year.
Just three days before he went missing, he spoke in an interview about the risks he faced on his way into Bakhmut to provide aid.
He said he had to choose between going on foot and being slow, but less visible, or going by car and being fast, but risk being spotted by drones.
Mr Bagshaw lived in New Zealand, with his family saying that he went to Ukraine because he believed it to be the "morally right thing to do".
They added that they were "immensely proud" of his work delivering food and medicines and assisting elderly people to move from near the front line.
