The bodies of three men have been found bound in Bucha with several gunshot wounds in some cases, which police say indicate that they had been tortured.
Ukraine says more than 1,000 bodies have been discovered in or around Bucha, a town northwest of Kyiv, with many some showing signs of torture. They were found after Russian troops withdrew earlier this month.

The apparent evidence of atrocities has prompted calls from several countries, as well as the UN and the International Criminal Court (ICC), for investigations to determine whether war crimes were committed.
In a video posted to YouTube on April 30, Kyiv regional police chief Andriy Nebytov said bullet wounds in the men's extremities showed they had been tortured, adding: "Finally, each of the men was shot in the ear.”
The video also contained images purporting to show the grave and the bloodied bodies, with faces blurred out.
Nebytov said the men were found in shallow graves in woods near the village of Myrotske, close to what had been Russian military positions. He said they were blindfolded with their hands tied and some were gagged. The men's clothes showed they were civilians, he added, although their identities were not known as their faces had been disfigured by torture.
Nebytov said forensic laboratories had now examined a total of 1,202 bodies of civilians believed to have been killed by Russian occupiers in the Kyiv region.
Despite overwhelming evidence to the contrary, Russia has denied targeting civilians since it launched its unprovoked war in Ukraine on February 24.
