A missile strike targeted an industrial plant in the city of Kirov, located in northeastern Russia, triggering a fire that authorities later extinguished.
The attack resulted in six deaths and injured 32 people, according to regional officials.
Explosions disrupted electricity and water supplies across several districts of the city, prompting emergency response efforts.
Kirov lies approximately 900 km from Moscow and about 1,350 km from the Ukrainian border.
The regional governor announced the casualty figures and infrastructure damage through a public messaging channel.
