At 0:07 AM, the alert was extended to the Pochepsky District, also noting the movement of a large number of drones into the rear.

Residents of the Bryansk region are advised to take precautions: when the "Attention All" signal sounds, seek shelter in windowless buildings, avoid windows, avoid using vehicles for cover, and avoid hiding under building walls.
