Officials say a Russian drone barrage has targeted the center of Kharkiv, injuring nine people and damaging a maternity hospital in Ukraine’s second-largest city.

The latest assault included more drones in a single night than Russia used in the entire month of July last year.

An U.S. official says some weapons shipments to Ukraine have resumed, as the country's leader seeks more urgent support from his partners.

Ukrainian officials say Russia has fired more than 700 attack and decoy drones at Ukraine overnight. That tops previous nightly barrages for the third time in two weeks.

Russia launched a large-scale aerial assault on Ukraine’s capital Kyiv in the early hours of Thursday, marking a second consecutive night of ferocious attacks on the country, as Russia ramps up its bombardment more than three years into the war.
