Overview

• Multiple large drones were reported over Aalborg, Billund, Esbjerg, Sønderborg and the Skrydstrup air base, forcing temporary closures that included a repeat shutdown at Aalborg overnight into Friday.
• Authorities described a systematic operation by a “professional actor” and raised the national police alert to heightened, but they declined to shoot the drones down due to safety concerns near populated areas.
• Denmark is weighing NATO Article 4 consultations after talks with Secretary General Mark Rutte, as France offered to help safeguard Danish airspace and police increased security around critical infrastructure.
• Attribution remains unresolved: Denmark’s military intelligence says the culprit is unknown, Latvia’s foreign minister says Denmark told allies state actors were responsible, and Russia’s embassy rejects involvement as a staged provocation.
• EU ministers are meeting to discuss joint anti-drone defenses as officials link the Danish incidents to a wider pattern that includes Polish and Romanian drone incursions and a recent Russian fighter-jet violation of Estonian airspace.
