A number of civilians were wounded while inhabitants in eastern districts were plunged into darkness and encountered disruption to drinking water, per reports from city officials.

Moscow has intensified assaults on energy facilities over the last fortnight, while Ukrainian leadership has called for "substantial measures" from partner nations to apply pressure on Moscow.
"The necessity is not superficial actions but strong steps - from the America, Europe and the major economies - in providing air defence systems and enforcing penalties," was stated in a online statement.
Officials stated that 450 drones and more than 30 projectiles targeted the country's power systems, characterizing such assaults as "premeditated" and against "essential services" as the weather cools.
Government representatives said Moscow was "inflicting a massive strike" and technical staff were working to fix the damage.
A barrage of missiles struck energy infrastructure and apartment buildings in Kyiv.
Multiple people wounded in the strikes on the city have been hospitalized, as confirmed by municipal representatives.
