The "mass killing of civilians" could be even worse in other cities than it is in the city of Bucha, Ukraine's President Zelensky has warned.
In a video speech released in the early hours of Tuesday morning, Mr Zelensky said: "At present, there is information about more than 300 people killed and tortured in Bucha alone. It is likely that the list of victims will be much larger when the whole city is checked. And this is only one city.
"There is already information that the number of victims of the occupiers may be even higher in Borodyanka and some other liberated cities. In many villages of the liberated districts of the Kyiv, Chernihiv and Sumy regions, the occupiers did things that the locals had not seen even during the Nazi occupation 80 years ago."
