Anton Gerashchenko, an adviser to the Ukrainian interior minister, reported this on Telegram, according to Ukrinform.
According to him, a mass grave with civilian Ukrainians killed by Russian invaders was found in the village of Buzova.
"Eyewitnesses also say that there is a burnt-out car nearby, in which a 17-year-old teenager was burnt alive and a woman lost half of her head," Gerashchenko wrote.
He added that local authorities believe that at least 50 locals had been killed by the occupiers.
The towns of Irpin, Bucha, Hostomel and the entire Kyiv region were liberated from Russian control in early April. Mass killings of civilians were recorded in the liberated towns and villages.
According to Ukraine's Prosecutor General Iryna Venediktova, the bodies of 1,222 civilians killed by Russian invaders were found in the Kyiv region.
