During the night, Moscow's missile and drone strikes have caused electricity outages in large parts of Ukraine's capital, Kyiv.
Nine people were hurt while local people in eastern districts were left without electricity and faced disruption to drinking water, per reports from local authorities.
Simultaneously, a minor was lost their life in a different assault in the Zaporizhzhia region in the country's south-east, as reported by area administrators.
Moscow has escalated strikes on electrical systems over recent weeks, while officials has called for "substantial measures" from partner nations to apply pressure on Russia.
"What's needed is not window dressing but firm measures - from the United States, European nations and the Group of Seven - in providing protection systems and applying sanctions," mentioned in a online statement.
Authorities reported that numerous aerial vehicles and over thirty projectiles struck energy facilities, describing such assaults as "cynical and calculated" and against "critical infrastructure" as winter approaches.
The energy minister said Moscow was "launching a major assault" and technical staff were working to fix the damage.
A barrage of missiles damaged power facilities and civilian homes in the capital.
Five out of the nine people injured in the strikes on the city have been transported for medical care, per statements from municipal representatives.
Regional authorities said the urban area endured intense attacks during nighttime hours. A minor was killed and several individuals were hurt.
The assaults come after periods of bombing campaigns in the area, portions of which remain under the control of Moscow's military.
All of Ukraine is in a state of readiness for sophisticated projectile assaults, which are harder to spot.
Authorities told journalists that Moscow was deliberately attempting to demolish the electrical infrastructure, with strikes already impacting gas facilities.
Authorities confirmed utility staff and government agencies were anticipating more assaults.
