Volodymyr Tsema-Bursov, 41, looks painfully thin in images taken in January when he was released during a prisoner exchange.
Volodymyr, who is 1.91 metres (6.2 feet) tall, lost nearly half his body weight and now weighs just 57 kilogrammes (125 lbs).
His ‘after’ photos could be mistaken for pictures taken at a World War II Nazi death camp.
