Gruesome evidence of atrocities carried out by Putin's men in the battered Ukrainian city of Mariupol. New trenches, the Russians allegedly buried at least 16,000 Mariupol residents in mass graves since mid-April. The heartrending video of mass graves comes after 200 bodies discovered in a Mariupol basement. 'Genocide by Russia in Mariupol' - another 5,000 people buried by public utilities by mid-March. Thousands of bodies still remain under the rubble, in natural cemeteries and in temporary mortuaries.
