Overview

• Overnight drones of unknown origin were detected over Aalborg, Esbjerg, Sønderborg and the Skrydstrup air base, leading to a temporary closure at Aalborg before operations resumed.
• Police reported the devices flew over a very wide area for hours with lights visible from the ground, could not be safely brought down, and no operators have been identified.
• Authorities opened an inquiry with the intelligence service PET and the armed forces, noting the Aalborg activity followed the same pattern as Monday’s incident at Copenhagen airport.
• Flight disruptions included four commercial services affected—two SAS, one Norwegian and one KLM—with an Amsterdam–Aalborg flight diverted to Billund.
• Officials described a hybrid threat by a professional actor, Russia denied involvement, and the government is weighing Article 4 consultations and legal changes to bolster counter‑drone powers.
