The family of a British fighter captured in Ukraine fear for his welfare after he looked 'drained of colour' as he was paraded on Russian TV.
Aiden Aslin, 28, from Newark, Notts., was forced to surrender after his unit ran out of ammunition and food in the besieged city of Mariupol.
Kremlin state TV has now broadcast footage of the Brit with a gash on his forehead, sparking concerns about his treatment in captivity.
The Brit was forcibly interviewed by a Russian journalist who asked him various questions about his time in Ukraine.
The interviewer asked him 'Tell me, did you kill people?', with Aiden replying 'I don't know'.
He then added: "I didn't do any fighting."
When asked if he saw how people were killed, Aiden looked off camera before answering 'no'.
His brother, Nathan Wood, 25, said Aiden looked 'awful' and 'absolutely exhausted' in the images.
He said: "It is so shocking for our family to see Aiden in that state.
"What have the Russians done to him? He looks awful, absolutely exhausted. His face is drained of colour.
"How has he got such a big red mark on his forehead? That looks like he's been hit with a rifle butt."
Aiden's mum, Ang Wood, is convinced the images are real due to her son's distinctive 'Happy Days' tattoo.
She said it looked like her son had been 'beaten up' and called on Vladimir Putin to respect Aiden's rights under the Geneva Convention.
The mum added: “I'm in bits. My son will be scared just as we are.
"Aiden is a serving member of the Ukrainian armed forces and as such is a prisoner of war and must be treated with humanity.
"It is time now for the British Government to get involved. and help secure Aiden's release because he is still a British citizen.
"Possibly there is hope for a prisoner swap arranged by the Ukrainians."
Aiden called his family in the early hours of Tuesday, telling them his unit was out of ammunition and food and had been ordered to surrender.

He told them the 36th Marine Brigade had been fighting for 48 days straight and was exhausted.
As many as 1,000 men from the 36th - 300 of them wounded - were said to have been taken prisoner.
Aiden, a British-Ukrainian dual citizen, has been a member of Ukraine's army for years.
He previously fought alongside the Kurdish YPG against Isis in Syria in 2015 and 2016.
