John Harding moved to Ukraine in 2018 and has appeared in a video appealing for help from Boris Johnson. He is a captive of pro-Russian separatists in the self-proclaimed Donetsk People's Republic (DPR) who told him he could face the death penalty. He was captured in May, while fighting with the Azov regiment of the Ukrainian National Guard, when Ukrainian units defending the south-eastern city of Mariupol were forced to surrender. Friends and family of Mr Harding confirmed to the BBC it was him in the video, and his family are being supported by the Foreign Office. He had been in eastern Ukraine's Donbas region to use his skills as a combat medic and help in the fight against pro-Russian rebels. Also, British aid worker Paul Urey, died while being held by pro-Russian separatists. DPR Officials said he died on 10 July from underlying health conditions and ‘stress’. Pray for the families whose fathers, brothers and sons are being held in appalling conditions.
