Efforts are underway to evacuate the last group of Ukrainian fighters who doggedly defended a steel mill in Mariupol for weeks, Ukrainian officials said. “The Supreme Military Command ordered the commanders of the units stationed at Azovstal to save the lives of their personnel,” the General Staff of the Armed Forces of Ukraine said. "Mariupol defenders are heroes of our time." More than 260 Ukrainian troops were evacuated to areas controlled by Russian-backed separatists. The Kremlin called the exodus a mass surrender. Russian Defense Ministry video shows troops patting down and searching the fighters. Some were on stretchers as they were loaded onto the buses. Ukraine Minister for the Reintegration Irina Vereshchuk said a prisoner exchange will take place for the more than 50 wounded soldiers, when their condition stabilizes, along with more than 200 other fighters evacuated through a humanitarian corridor.
