"What is required is not window dressing but strong steps - from the US, European nations and the Group of Seven - in providing defensive weapons and applying sanctions," mentioned in a online statement.
Officials stated that 450 drones and several dozen missiles struck Ukraine's energy infrastructure, describing such attacks as "cynical and calculated" and against "everything that sustains normal life" as temperatures become colder.
Government representatives said Moscow was "conducting extensive attacks" and maintenance teams were laboring to restore power.
A wave of strikes damaged energy infrastructure and civilian homes in the capital.
Multiple people wounded in the assaults on the capital have been taken to hospital, as confirmed by local officials.
Area administrators said the urban area experienced intense attacks during nighttime hours. A young boy was killed and three other people were wounded.
The attacks come after nights of aerial attacks in the region, sections of which are currently controlled by Moscow's military.
The whole nation is in a state of readiness for advanced weapon attacks, which are tougher to spot.
Authorities told the media that Moscow was purposely seeking to demolish the electrical infrastructure, with assaults already disrupting fuel infrastructure.
Officials stated energy workers and authorities were bracing for additional strikes.
