Petersburg media outlet Fontanka disclosed that between 03:53 and 05:11, Pulkovo Airport, the primary international airport in the city, enacted the Kover (Carpet) protocol—an operational procedure designed to safeguard the airfield when potentially hazardous objects are identified in the airspace. Allegedly, the cause of this interruption was a Ukrainian drone.
