During the night, Moscow's aerial assaults have led to power cuts in extensive areas of Ukraine's capital, Kyiv.
Nine people were hurt while residents in eastern districts were left without electricity and encountered interruptions to drinking water, according to municipal leaders.
Meanwhile, a minor was killed in a distinct Russian drone strike in the Zaporizhzhia area in the southeastern part, based on information from regional authorities.
Moscow has increased attacks on electrical systems over recent weeks, while Ukrainian leadership has demanded "real steps" from international partners to increase pressure on Moscow.

A barrage of missiles struck energy infrastructure and apartment buildings in the capital.
Multiple people wounded in the assaults on the capital have been hospitalized, per statements from municipal representatives.
Local officials said the city experienced significant strikes throughout the evening. A minor was killed and three other people were hurt.
The assaults succeed evenings of aerial attacks in the region, portions of which are occupied by Moscow's military.
The entire country is under warning for sophisticated projectile assaults, which are more difficult to identify.
Government officials told journalists that Moscow was intentionally trying to demolish the country's energy grid, with strikes already affecting fuel infrastructure.
Authorities confirmed utility staff and officials were bracing for additional strikes.
