A 12-year-old girl was killed and three others injured in a Russian drone strike on Ukraine’s Dnipropetrovsk region, local officials said.

Russia launched drone strikes on civilian areas of Ukraine in another deadly overnight attack, Ukrainian authorities said on Tuesday, while Kyiv dismissed Russian President Vladimir Putin’s declaration of a unilateral three-day ceasefire beginning next week.

The assault damaged homes in Ukraine’s central Dnipropetrovsk region, authorities said, killing a 12-year-old girl and wounding three others, including a six-year-old.

Russia also launched 20 drones and 31 powerful guided bombs at Kharkiv, the second-largest Ukrainian city, according to officials. Debris from an intercepted Russian drone started a fire in a neighbourhood of the capital, Kyiv, authorities said.

Meanwhile, Russia’s defence ministry said on Tuesday that its forces destroyed 91 Ukrainian drones overnight.
