Fifty-seven people were buried in a mass grave in Bucha, a town outside Kyiv recently retaken by Ukrainian forces from Russian troops, a local official said Sunday, showing AFP a slit trench where the bodies lay.
"Here in this long grave, 57 people are buried," said Serhii Kaplychnyi, who identified himself as head of the rescue services in Bucha, organizing the recovery of the bodies.
The mass grave is behind a church in the town center.
Roughly 10 bodies were visible, either unburied or partially covered by the earth.
Some of the bodies were concealed in black zip-up body bags while others were in civilian clothing.
