A civilian disaster is growing in Ukraine as attempts to evacuate residents of besieged port city Mariupol failed for a second day, with President Volodymyr Zelensky denouncing “murder” as he warned of more shelling to come on Monday.

New shelling and attacks have sent soaring numbers of refugees fleeing, sometimes under fire, as the death toll mounts.

“It’s murder, deliberate murder,” Mr Zelensky raged in an address.

“We will not forgive, we will not forget, we will punish everyone who committed atrocities in this war on our land.

“There will be no quiet place on this Earth except the grave.”

He said Russia had announced new shelling for Monday of defence targets in Ukrainian cities and denounced what he branded the “silence” of Western governments failing to speak out.

Russian forces stepped up their shelling of Ukrainian cities in the centre, north and south of the country late on Sunday, presidential adviser Oleksiy Arestovich said.

“The latest wave of missile strikes came as darkness fell,” he said on Ukrainian television.

He said the areas that came under heavy shelling include the outskirts of Kyiv, Chernihiv in the north, Mykolaiv in the south, and Kharkiv, the country’s second-largest city.
