Burned cars. Blackened apartments. Demolished roofs. Streets crawling with journalists and investigators, documenting bodies. Days after Russian forces retreated from the Kyiv area, investigators and volunteers are beginning the long, grim work of chronicling what U.S. officials have described as a "troubling campaign" of brutality against civilians. Ukrainian officials say the bodies of more than 400 civilians were found in towns around Kyiv after Russian forces withdrew. In Bucha, more than 320 civilians were killed, Mayor Anatolii Fedoruk said Wednesday. While Russian officials continue to deny the allegations and attribute the killings to Ukrainian forces, satellite images shared by numerous outlets — including The New York Times, CNN and Reuters — show bodies were lying on the streets of Bucha weeks ago, during Russian occupation. "We need help fast as possible because every day of war will be worse," Kyiv resident Vladimir Basovskyi said. 📸: Efrem Lukatsky, AP / Vadim Ghirda, AP
