Overview

• Airspace over Aalborg closed late Thursday and reopened about 55 minutes later, with a KLM flight turning back to Amsterdam and a SAS departure canceled, according to police and flight trackers.
• In the previous night’s wave, drones were reported over Aalborg, Esbjerg, Sønderborg and the Skrydstrup air base, temporarily shutting Aalborg and disrupting four commercial flights including two SAS, one Norwegian and one KLM, with one Amsterdam–Aalborg flight diverted to Billund.
• Police say they could not safely shoot down the drones, no operators were apprehended, and the devices were seen flying with lights; a joint investigation with PET and the military is ongoing.
• Defense Minister Troels Lund Poulsen called the incidents a hybrid attack by a professional actor, military intelligence said attribution remains unknown, and officials warned the risk of Russian sabotage is high.
• The government is preparing legal changes to let critical‑infrastructure operators neutralize drones, considering NATO Article 4 consultations, and Norway separately seized a drone near Oslo and arrested one person for illegal operation.
