The attack occurred during an agreed 12-hour ceasefire in six cities in Ukraine, including Mariupol, to allow civilians to escape.
An official from Mariupol has said the three people - including one child - have been killed. At least 17 people are reportedly wounded, including members of staff and women in labour, with move believed to be buried under the rubble.
Responding to the reports, Dr Camilla Kingdon, RCPCH President, said:
These reported attacks are deplorable. The news about the children’s hospital in Mariupol follows devastating reports of an orphanage bombed, a neonatal unit treating their patients in a basement bomb shelter and the number of those fleeing Ukraine reaching two million.
The UK Government rightly recognises this as a humanitarian emergency but so much more is needed, immediately, to protect and secure the safety of children and young people in Ukraine.
We’re calling for action from Government to ensure safe passage of pregnant women, babies and children out of Ukraine and for an increase in the number of refugees being accepted into the UK, including children and young people.
