Russia's Defense Ministry said that air defenses downed 174 Ukrainian drones over 13 regions early Friday. It added that three Ukrainian Neptune missiles were also shot down over the Black Sea.
Ukraine struck airfields and other military targets in Russia, such as fuel storage tanks and transport hubs, the Ukrainian General Staff said.
Also, a locomotive derailed early Friday in the Belgorod region after the track was blown up, Belgorod Gov. Vyacheslav Gladkov said. Russia has recently accused Ukraine of sabotaging the rail network.
In Kyiv, multiple explosions were heard for hours as falling drone debris sparked fires across several districts, said Tymur Tkachenko, head of the Kyiv City Administration. He urged people to seek shelter.
