Around 300 people have been killed in Mariupol as a result of a Russian airstrike on a theatre.
The attack was widely-condemned, as hundreds of people were sheltering in the theatre at the time of the strike - with the word 'children' visible from the sky on either side of the building.
On top of that, the Mariupol City Council has now published a desperate letter asking for help, stressing there were "more and more deaths from starvation" - including children.
