Ukraine’s President Volodymyr Zelensky shared grim footage of what he says is what is left of a children’s hospital in Mariupol after it was hit by a Russian airstrike.

Ukraine’s regional governor Pavlo Kyrylenko said on Wednesday that the airstrike was during an agreed ceasefire that was meant to allow the evacuation of civilians from besieged Mariupol, which is in the throws of a deteriorating humanitarian catastrophe as the large city is without water and basic services.

Kyrylenko said that seventeen people were wounded in the attack, including women in labor, reported Reuters on Wednesday.
