The decomposing bodies of 200 people were found in the basement of a bombed-out apartment building in battered Mariupol, authorities said Tuesday, marking the latest in a series of dismal discoveries since the Russian invasion of Ukraine began three months ago.

Mayoral adviser Petro Andryushchenk said local residents had refused Russian demands to collect the bodies of the dead, so Russia’s Ministry of Emergencies left the bodies amid the rubble. 

Mariupol has been left in ruins by weeks of missile attacks. Last week the last Ukrainian fighters surrendered, giving Russia complete control of the city that was home to 450,000 people before the war. An estimated 100,000 remain. Mayor Vadym Boychenko claims the Russian bombardment of the city killed thousands of civilians.

Earlier, Ukrainian President Volodymyr Zelenskyy accused Russia of attempting to inflict as much death and destruction as possible on his country.

“There has not been such a war on the European continent for 77 years,” Zelensky said in his nightly address.
