Regional authorities said the city experienced significant strikes throughout the evening. A minor lost their life and three other people were injured.
The assaults succeed periods of air raids in the territory, portions of which are currently controlled by Russian forces.

Government officials told reporters that Russia was deliberately attempting to damage the national power system, with attacks already affecting gas facilities.
