Ukraine war: Children buried under rubble after Russian airstrike hit maternity hospital in Mariupol, President Zelenskyy says

Children have been buried under rubble after a Russian airstrike hit a hospital in Mariupol, Ukraine's President Volodymyr Zelenskyy has said.

The president tweeted that children were among people "under the wreckage", calling the strike an "atrocity".

Mariupol's city council said the maternity and children's hospital had been destroyed, adding that it did not know any casualty figures but that "the destruction is colossal".

The governor of Donetsk region said 17 people, including women in labour, were wounded in the airstrike.

The governor added that the airstrike happened during an agreed ceasefire period to allow civilians to safely escape.

And video footage from the hospital shows bloodied pregnant women being brought out on stretchers.

In the grounds there is a huge crater, estimated to be about 20ft deep and 30ft wide. According to former senior RAF Office Air Marshall Edward Stringer, the crater seems to be evidence of a large, general-purpose bomb of at least 1,000lbs - probably 2,000lbs.

He told Sky News this was not likely to be a cluster bomb and is more likely to have been a sophisticated missile.

Prime Minister Boris Johnson has condemned the attack as "depraved" and said the UK is exploring "more support” for Ukraine to defend itself, adding: "We will hold Putin to account for his terrible crimes."

The Ukrainian government said 1,170 civilians have been killed in Mariupol since Russia began its invasion, citing the city's deputy mayor. The city council has put the figure at 1,207 civilians.

People in the city have been forced to get water from melting snow, while some bodies lay in the street from intense bombardment.

Mariupol's mayor Vadim Boychenko said: "I am sure that the time will come when all these occupiers will sit in the dock in The Hague. And this war crime will be punished, and the perpetrators will burn in hell."

The city council said it has endured nine days of genocide, adding: "We will never forgive. We will never forget. Hold on, Mariupol."

Yesterday a six-year-old girl named Tanya died alone from dehydration in the ruins of her home in the city after her mother was killed in shelling by Russian forces, Ukrainian authorities said.

New ceasefires were announced on Wednesday morning to allow thousands of civilians to escape from towns around Kyiv as well as the southern cities of Mariupol, Enerhodar and Volnovakha, Izyum in the east and Sumy in the northeast.

Previous attempts to establish safe evacuation corridors largely failed because of what the Ukrainians said were Russian attacks.

But Russian President Vladimir Putin, in a telephone call with Germany's chancellor, accused militant Ukrainian nationalists of hampering the evacuations.
