During the night, Moscow's missile and drone strikes have caused electricity outages in large parts of Ukraine's capital, Kyiv.
Nine people were injured while local people in eastern districts were plunged into darkness and dealt with interruptions to drinking water, per reports from local authorities.
At the same time, a young boy was killed in a different assault in the Zaporizhzhia area in the country's south-east, based on information from local officials.
Russian forces has escalated attacks on electrical systems over the last fortnight, while Ukrainian leadership has called for "concrete actions" from international partners to increase pressure on Russia.
"What's needed is not window dressing but strong steps - from the US, European nations and the Group of Seven - in delivering air defence systems and applying penalties," mentioned in a social media post.
Authorities reported that numerous aerial vehicles and over thirty projectiles targeted energy facilities, labeling such strikes as "cynical and calculated" and against "essential services" as temperatures become colder.
Energy officials said Moscow was "conducting extensive attacks" and repair crews were striving to fix the damage.
A series of attacks damaged power facilities and residential structures in the capital.
Several of the people injured in the attacks on the city have been hospitalized, as confirmed by municipal representatives.
Local officials said the urban area came under significant strikes during nighttime hours. A minor lost their life and three other people were injured.
The assaults come after periods of aerial attacks in the region, sections of which are occupied by invading troops.
The entire country is on alert for advanced weapon attacks, which are tougher to spot.
Authorities told journalists that Moscow was purposely seeking to destroy the electrical infrastructure, with strikes already disrupting gas facilities.
Officials stated technical personnel and government agencies were preparing for additional strikes.
