Wednesday's attack on a hospital in Mariupol, where a maternity and children's wards are located, is horrific, UN Secretary-General António Guterres said.

"Civilians are paying the highest price for a war that has nothing to do with them," he said on Twitter.

"This senseless violence must stop. End the bloodshed now," the UN Secretary General said.

As reported with reference to Head of Donetsk regional military administration Pavlo Kyrylenko, as a result of an air raid by Russian troops on a maternity hospital in the center of Mariupol, some 17 people among the staff and women in labor were wounded. According to him, the air attack was carried out during the ceasefire in Mariupol, which, among other things, was confirmed by the Russians, for the work of humanitarian corridors in the city.
