He said besides the bodies in the mass grave, corpses were also found in the streets of the town.

According to the Mayor, 15,000 people lived in Makariv before Russia began its invasion on February 24 and now less than 1,000 remain.

Meanwhile, 52 people are killed, including five children, in a rocket attack on a train station in the eastern Ukrainian city of Kramatorsk that is being used for civilian evacuations, according to Donetsk region governor Pavlo Kyrylenko.

Ukrainian President Volodymyr Zelensky describes Russia as an "evil with no limits" after the attack and calls for a "firm global response".

US President Joe Biden accuses Russia of being behind the attack, calling it a "horrific atrocity", while French Foreign Minister Jean-Yves Le Drian deems it a "crime against humanity".

Russia's defence ministry accuses Kyiv of carrying out the attack, saying it wanted to use fleeing residents "as a 'human shield' to defend the positions of Ukraine's Armed Forces".
