Ukrainian authorities scrambled to counter the consequences of the latest bombardment, part of a recurring cycle of urban smash-and-repair that has brought little change in the course of the war.

Overall, Russia launched 81 missiles and eight exploding Iranian-made Shahed drones Thursday, according to Ukraine’s chief commander of the armed forces, Valerii Zaluzhnyi.

Russian forces have spent months trying to capture the city as part of their offensive in eastern Ukraine, and the area has seen some of the bloodiest ground fighting of the war.
