Flights were grounded in both Denmark and Norway after unauthorized drones were detected in the airspace near major airports overnight. The disruptions affected tens of thousands of passengers as flights were diverted or delayed across the region.
Danish Prime Minister Mette Frederiksen described the incident as possibly the “most serious attack on Danish critical infrastructure to date.” Norwegian authorities also confirmed broad disruptions.
Investigations are underway on whether the drone incursions were coordinated, with speculation about Russian involvement in light of regional tensions. NATO condemned airspace violations over Estonia just days earlier, heightening security concerns across Northern Europe.
Analysts say the episodes underline growing vulnerabilities in national air defense systems and may prompt stricter regulations and countermeasures for drone activity.
