During the exercise, air raid sirens will be sounded across the city, and residents are expected to follow blackout protocols.

The purpose of the exercise is to assess how quickly systems can respond, identify gaps and ensure smoother coordination during real emergencies. It is not indicative of any imminent attack or developing crisis.
Residents who notice temporary blackouts or increased emergency activity have been advised to remain calm and rely only on official communication channels for updates, as the drill is a planned simulation designed to improve preparedness rather than signal danger.
