Reports have been coming in about a Russian strike on a maternity hospital in the south-eastern city of Mariupol - which has already suffered days of shelling.
Now President Zelensky has tweeted footage from the incident - which he described as a "direct strike" - it shows destroyed rooms along a corridor in the building.
"People, children are under the wreckage. Atrocity! How much longer will the world be an accomplice ignoring terror?" he says.
Zelensky demanded a no-fly zone over the country to stop Russian aircraft from flying - something the US and other Nato countries have ruled out.
"Close the sky right now! Stop the killings! You have power but you seem to be losing humanity," he urged.
The city council said the strike had destroyed a maternity ward and a children's ward.-BBC
