Russian attacks left Ukraine's southeastern regions of Dnipropetrovsk and Zaporizhzhia almost entirely without power, the country's energy ministry said on Wednesday night.

Critical infrastructure was operating on reserve power, it said in a statement on Telegram, while officials reported disruptions to water supplies and internet services as well.

Russia has recently intensified attacks aimed at paralyzing power supplies during a harsh winter. Ukraine's energy system is under enemy attacks every day, and energy workers are operating in extremely difficult conditions to provide people with light and heat, stated Prime Minister Yulia Svyrydenko.

Deteriorating weather conditions have further strained critical infrastructure as temperatures plunge.

Emergency restoration work in the regions affected by the attack will begin immediately as soon as the security situation allows, noted state energy company Ukrenergo.

Dnipro city Mayor Borys Filatov mentioned that all hospitals in the city had switched to generators, ensuring that water treatment processes continue uninterrupted.

School holidays were extended due to the ongoing power cuts, which exemplify the challenges the people of Ukraine are currently facing due to the ongoing conflict.

Pressing ahead with the restoration of services, local leaders claim there's an ongoing effort to manage water utilities and respective public services despite the entirety of Zaporizhzhia being under blackout conditions.

As Ukraine approaches the fourth anniversary of the ongoing invasion, it’s reported that foreign allies have been slow to provide security assurances to counter renewed aggression from Russia.
