From a New York Times story headlined “Nine Accounts of Surviving a Russian Siege”:

In early March, the Russian Army encircled Mariupol, Ukraine, a southern port city on the Black Sea. A siege and relentless bombardment followed. Food and water quickly grew scarce, and gas, electricity, internet access and cellphone service became nonexistent.

Early attempts to create humanitarian corridors — to allow civilians to get out of the city and to get food, water and supplies in — failed under Russian shelling. As the siege continued, the dead were covered and left outside because it was too dangerous to collect them. Russians bombed a maternity hospital and a theaterwhere up to 1,000 people were sheltering.
