Two U.K. soldiers captured fighting for Ukraine appeal for prisoner swap in Russian video

Two British soldiers fighting with the Ukrainian army have appeared on Russian state television after being captured in the besieged port city of Mariupol in southern Ukraine.

Several propaganda clips aired on Rossia 1 and RT channels on Sunday and Monday, picturing U.K. citizens Shaun Pinner, 48, and Aiden Aslin, 28. They fought in Mariupol as part of Ukraine's 36th Marine Brigade.

On Sunday, Pinner, who appeared to be tired and bruised, spoke to Russian TV war reporter Andrey Rudenko and gave some details about the battle of Mariupol.
