During the night, Moscow's missile and drone strikes have led to electricity outages in multiple districts of Ukraine's capital, Kyiv.
A number of civilians were hurt while residents in eastern districts were left without electricity and encountered problems to water supplies, according to municipal leaders.
At the same time, a minor was killed in a distinct assault in the southeastern region in the southeastern part, based on information from regional authorities.
Moscow has increased assaults on electrical systems over the past few days, while the country's government has requested "concrete actions" from allies to increase pressure on Russia.
"What is required is not superficial actions but strong steps - from the US, Europe and the major economies - in delivering protection systems and applying penalties," he wrote in a social media post.
Authorities reported that hundreds of unmanned aircraft and several dozen missiles struck the country's power systems, characterizing such attacks as "premeditated" and against "essential services" as the weather cools.
Energy officials said Moscow was "inflicting a massive strike" and repair crews were working to restore power.
A barrage of missiles struck power facilities and apartment buildings in the capital.
Several of the people injured in the assaults on the capital have been taken to hospital, according to city authorities.
Local officials said the metropolitan region experienced significant strikes during nighttime hours. A seven-year-old child died and multiple civilians were wounded.
The attacks succeed periods of bombing campaigns in the territory, portions of which are currently controlled by Russian forces.
The entire country is on alert for advanced weapon attacks, which are harder to detect.
Authorities told journalists that Moscow was deliberately attempting to damage the country's energy grid, with attacks already affecting fuel infrastructure.
He said energy workers and officials were anticipating more assaults.
