Overnight, Moscow's aerial assaults have led to electricity outages in multiple districts of Ukraine's capital, the Ukrainian capital.
Nine people were hurt while inhabitants in eastern districts were plunged into darkness and encountered interruptions to water systems, as stated by local authorities.
Meanwhile, a minor was killed in a different aerial attack in the southeastern region in the country's south-east, based on information from regional authorities.
Moscow has intensified assaults on energy facilities over the last fortnight, while Ukrainian leadership has called for "substantial measures" from allies to exert influence on Moscow.
"The necessity is not window dressing but decisive action - from the US, the EU and the major economies - in delivering defensive weapons and applying restrictions," he wrote in a online statement.
He said that 450 drones and more than 30 projectiles attacked energy facilities, describing such attacks as "strategic and deliberate" and against "essential services" as the weather cools.
Energy officials said Russia was "conducting extensive attacks" and technical staff were striving to fix the damage.
A series of attacks damaged power facilities and residential structures in Kyiv.
Several of the people hurt in the assaults on the capital have been taken to hospital, according to local officials.
Regional authorities said the metropolitan region endured significant strikes during nighttime hours. A seven-year-old child died and three other people were hurt.
The attacks succeed periods of bombing campaigns in the area, portions of which are currently controlled by Moscow's military.
The entire country is on alert for advanced weapon attacks, which are more difficult to identify.
Authorities told reporters that Moscow was intentionally trying to demolish the national power system, with strikes already disrupting energy systems.
Authorities confirmed technical personnel and government agencies were bracing for further attacks.
