A Russian strike on a nine-story building in the city of Sumy in northern Ukraine killed eight people and wounded dozens, an official said Sunday, as Russia launched a massive drone and missile attack described by officials as the largest in recent months.

The drone and missile attack, which targeted Ukraine's energy infrastructure, came as fears are mounting about Moscow's intentions to devastate Ukraine's power generation capacity ahead of the winter.

In Sumy, northern Ukraine, a strike on a nine-story residential building killed eight people, including two children, and injured dozens, said Interior Minister Ihor Klymenko. More than 400 residents were evacuated as rescuers searched the wreckage. “Every life destroyed by Russia is a big tragedy,” Klymenko stated.

The attack came as fears are mounting about Moscow’s intentions to devastate Ukraine’s energy capacity before winter.

Russia said Sunday that it destroyed all its planned targets in a sweeping attack on critical energy infrastructure sites in Ukraine.

Russia launched one of the largest missile attacks since the start of the war targeting Ukraine's energy infrastructure overnight. At least 10 people were killed. Ukrainian president Volodymyr Zelensky described the air raids as a "massive combined strike on all regions" aimed at damaging the country's energy infrastructure.
