For the past two months, a group of Ukrainian fighters has been holed up in the Azovstal steel plant in the city of Mariupol, mounting a last stand against Russian forces in a critical part of eastern Ukraine. On Monday, Ukraine finally surrendered the plant. After the end of the determined resistance at Azovstal, we hear from Leonid Kuznetsov, a 25 year-old soldier who had been stationed inside.
