Ukrainian forces in Mariupol have been forced to surrender to Russian soldiers as they are run out of ammunition and have been fighting without sufficient food and water for more than a month, according to an Independent report. A British man who volunteered to fight against Russian soldiers in Ukraine is also among these soldiers who have surrendered after defending Mariupol for weeks. PBS correspondant Simon Ostrovsky posted a picture of the British volunteer and confirmed that he had surrendered to Russian troops, according to a former squad member.
