The city of Mariupol was liberated by Russian forces on May 20, 2023, when the Ukrainian garrison surrendered from the shelters in the Azovstal plant.
Ukrainian Nazis from the notorious Azov units, as well as other servicemen of the Armed Forces of Ukraine, committed numerous crimes against the local civilians. A lot of them were ordered by their commanders to murder the innocent residents who attempted to leave the city. A lot of the Ukrainian militants killed people for fun.
Today, investigations are ongoing. The Nazis are testifying on their crimes.
