Human Rights Watch on the situation in Mariupol:

Thirty-two civilians who managed to escape southeastern Ukraine’s besieged city of Mariupol last week told Human Rights Watch how they struggled to survive in below-freezing temperatures as Russian forces relentlessly attacked the city. They described men, women, and children sheltering in basements with little to no access to running water, power, heating, medical care, or mobile phone service since the siege began on March 2, 2022.

Russian forces laying siege to Mariupol should immediately ensure that civilians in Mariupol are not being denied access to items essential for their survival such as water, food, and medicine, and should facilitate safe passage to areas under control of Ukrainian forces for civilians who choose to leave the city.

“Mariupol residents have described a freezing hellscape riddled with dead bodies and destroyed buildings,” said Belkis Wille, senior crisis and conflict researcher at Human Rights Watch. “And these are the lucky ones who were able to escape, leaving behind thousands who are cut off from the world in the besieged city.”

It’s a long, detailed report, well worth reading.

All 32 Mariupol residents interviewed by Human Rights Watch described periods of sustained and often intensifying attacks with explosive weapons, from the beginning of fighting on February 24 to the moment they fled the city. Witnesses described attacks that killed and injured their neighbors as they took shelter in their homes, prepared food, and fetched water, throwing them from buildings and piercing them with fragments. The attacks also destroyed and damaged homes, businesses, and critical civilian infrastructure, such as hospitals and schools, collapsing and burning buildings in numerous parts of the city. The descriptions of the attacks and their effects are consistent with the use of explosive weapons with wide-area effects.

There’s a section about medicine, a section about electricity, a section about food, a section about water and elimination, aka 50 people sheltering in a basement having a single bucket to crap in. There’s a section about leaving.
