"What is required is not symbolic gestures but decisive action - from the America, Europe and the Group of Seven - in delivering air defence systems and implementing penalties," he wrote in a social media post.
Authorities reported that numerous aerial vehicles and over thirty rockets struck energy facilities, describing such assaults as "cynical and calculated" and against "essential services" as temperatures become colder.
The energy minister said Russia was "inflicting a massive strike" and technical staff were laboring to repair systems.
A wave of strikes hit energy infrastructure and apartment buildings in the capital.
Five out of the nine people hurt in the attacks on the capital have been transported for medical care, as confirmed by municipal representatives.
Regional authorities said the urban area endured intense attacks throughout the evening. A seven-year-old child lost their life and three other people were hurt.
The assaults come after evenings of air raids in the region, sections of which are occupied by Moscow's military.
The entire country is under warning for sophisticated projectile assaults, which are tougher to spot.
Authorities told reporters that Moscow was purposely seeking to destroy the national power system, with strikes already impacting fuel infrastructure.
Authorities confirmed technical personnel and officials were preparing for more assaults.
