On Wednesday, March 9th, Russia bombed a maternity and children’s hospital in the city of Mariupol, Ukraine, marking the most violent fighting since the beginning of Russia’s invasion. The attack presented itself despite an agreement Russia made previously to cease fire for a period of 12 hours, which would’ve given refugees the opportunity to evacuate their cities safely.

Officials say three people were killed and at least 17 people were injured in the attack.

Outraged, President Zelensky of Ukraine persisted in his demand that NATO declare a “no-fly zone” over Ukraine. “You have power but you seem to be losing humanity,” Zelensky said over telegram after the attack. He announced the strike an “atrocity” and “final proof, proof of a genocide of Ukrainians taking place.”

Russia continues to strafe Mariupol, Ukraine “in any significant way” and that, so reported from officials, 1,300 Mariupol civilians have been killed since the initiation of the invasion.

A city administration building and a university in Mariupol a short distance away from the bombed hospital have been identified by CNN as other locations in the city hit by a Russian military strike.

The hospital’s attack triggered worldwide disapproval. The United Nations said it would follow up “urgently,” stating healthcare buildings should never “ever, ever be a target.”
