Two British fighters captured in the Ukrainian city of Mariupol have appeared on Russian state TV and asked Prime Minister Boris Johnson to help bring them home.
In footage broadcast on the Rossiya 24 state TV channel, Shaun Pinner and Aiden Aslin, who were captured while defending Mariupol against Russian attacks, asked to be exchanged for Viktor Medvedchuk, a pro-Russian oligarch who was arrested by the Ukrainian authorities on April 12.
