Diplomats working to find Aiden Aslin, who was forced to surrender to Russian troops with his unit in Mariupol
UK diplomats are working to determine the whereabouts of British nationals in Ukraine amid reports a man from Nottinghamshire has been captured by pro-Moscow forces while serving with the Ukrainian military.
Aiden Aslin, who is from Newark and has been fighting in the besieged city of Mariupol, was forced to surrender with his comrades earlier this week after they ran out of food and ammunition.
