"What is required is not superficial actions but decisive action - from the US, the EU and the major economies - in delivering air defence systems and enforcing sanctions," was stated in a online statement.
Officials stated that 450 drones and more than 30 rockets struck energy facilities, labeling such assaults as "strategic and deliberate" and against "everything that sustains normal life" as winter approaches.

A series of attacks struck electrical systems and apartment buildings in the capital.

Local officials said the city experienced intense attacks overnight. A minor lost their life and several individuals were wounded.
The strikes succeed evenings of aerial attacks in the territory, parts of which are occupied by invading troops.
