At least six people have died after Russia launched hundreds of missile and drone attacks on energy infrastructure and residential targets in Ukraine overnight.

A strike on an apartment building in the city of Dnipro killed two people and wounded 12, while three died in Zaporizhzhia.

In all, 25 locations across Ukraine, including the capital city Kyiv, were hit, leaving many areas without electricity and heating. Prime Minister Yulia Svyrydenko said on Telegram that major energy facilities were damaged in the Poltava, Kharkiv, and Kyiv regions, and work was under way to restore power.

In Russia, the defence ministry said its forces had shot down 79 Ukrainian drones overnight.

The Ukrainian air force reported that Russia had launched more than 450 exploding bomber drones and 45 missiles. Nine missiles and 406 drones were reportedly shot down.

The Ukrainian Energy Ministry indicated that there were power cuts in the Dnipropetrovsk, Chernihiv, Zaporizhzhya, Odesa, and Kirovohrad regions, but restoration work was ongoing.

Svyrydenko stated that critical infrastructure facilities have already been reconnected, and water supply is being maintained using generators.

Russia contends its strikes on energy targets are aimed at the Ukrainian military.

These attacks on Ukraine's energy infrastructure ahead of winter have become a recurring strategy in the ongoing conflict. Kyiv officials express deep concerns, suggesting that Moscow aims to depress both morale and the economy by destabilizing its energy network.

Ukrainian President Volodymyr Zelensky highlighted that the attacks underline the necessity for consistent Western sanctions on Russian energy to exert pressure on Moscow.

The missile strikes occurred shortly after the US granted Hungary a one-year exemption from restrictions on purchasing Russian oil and gas, which was considered a controversial move.

Zelensky reiterated that consuming Russian energy fuels the ongoing war, and emphasized the importance of sanctions. For every strike targeting energy infrastructure, he called for a proportional sanctions response against all facets of Russian energy.
