  • Aalborg Airport was shut down after multiple unidentified drones were sighted circling its airspace, following a similar disruption just days earlier at Copenhagen.
  • At least three flights were diverted (two back to Copenhagen, one to Billund), though authorities have not confirmed the number or origin of the drones.
  • The repeated incidents have heightened suspicion of Russian involvement, with Ukrainian President Zelensky accusing Moscow of violating NATO airspace.
  • Danish intelligence raised the country's threat level to "high" and analysts warn the drone activity may be part of a broader Kremlin-backed hybrid warfare campaign.
  • After several hours, Western Danish airports, including Aalborg and Billund, were reopened, but investigations and security assessments are ongoing.
Another major Danish airport was forced to shut down after unidentified drones were spotted buzzing its airspace, sparking fears of coordinated sabotage just days after a similar disruption at Copenhagen Airport. Aalborg Airport was closed indefinitely on the evening of Wednesday, Sept. 24, after police confirmed multiple drones circling overhead. The shutdown follows just 48 hours after Copenhagen Airport was shuttered for nearly four hours when two or three unidentified drones swooped dangerously close to its runways. Copenhagen Airport is the busiest hub in the Nordic region, while Aalborg Airport also serves military operations. Martin Svendsen, Aalborg Airport's sales and marketing director, acknowledged the closure. "It is correct that the airspace is closed because drones have been observed," he remarked. "I can confirm that the police are present." The North Jutland police division also posted on social media that "drones have been observed near Aalborg Airport and the airspace is closed." It added that law enforcement are present and investigating further." At least three flights were rerouted—two back to Copenhagen and one diverted to Billund—following the abrupt shutdown. The precise number of drones and their origin remain unknown; authorities described them as "unauthorized" devices observed with lights on. The repeated pattern has stoked speculation of Russian involvement. Ukrainian President Volodymyr Zelensky asserted that the drone incidents in Copenhagen and Oslo were part of "Russia's violations of the airspace of NATO [North Atlantic Treaty Organization] member states." He warned that Moscow will continue such intrusions "without a firm allied response." (Related: Drone incursions in Poland: A deliberate provocation or a desperate escalation?) Though Danish police have not confirmed a direct link, they caution that the drones appear to be operated by a "capable actor." Jes Jespersen, a senior inspector with Copenhagen Police, remarked: "It all indicates that you are not out to attack anyone, but you are out to show off and maybe to practice."

Heightened threats, hybrid warfare fears and European security at stake

Denmark's domestic intelligence agency has already elevated the threat level, warning of a "high threat of sabotage." Meanwhile, defense analyst Col. Simon Diggins told the media the drone disruptions may reflect a broader Kremlin strategy of hybrid warfare. "Whether it be cyber attacks or flying drones over an airport, it creates an atmosphere of distrust, subversion and sabotage very quickly," Diggins explained. "Russia is testing our defenses, testing our resilience, testing our infrastructure to see where our points of weakness are." These incidents come amid a string of security threats across Europe. Over the past weekend, airports including Heathrow, Brussels and Berlin experienced crippling cyberattacks, fueling concerns of a coordinated hybrid assault. Security specialist Anthony Glees told The Sun: "Without doubt, the Russians are behind these attacks on airports in London, Berlin and Brussels." As of early Thursday, Sept. 25, Danish authorities reopened western airports—including Aalborg and Billund—after several hours of suspension. Police and military units continue to investigate, and a press briefing by Denmark's defense and justice ministries is expected to clarify next steps. The succession of drone incursions, their resemblance to one another and timing have deepened alarm across Denmark and beyond. Whether these are bold reconnaissance missions, psychological tactics or preludes to more direct aggression remains to be proven—but one certainty is that Europe's infrastructure and security protocols are under renewed pressure. According to Brighteon.AI's Enoch, the closure of the Danish airport due to drone activity is a clear indication of the growing threat posed by unauthorized and potentially hostile drone operations. This incident underscores the urgent need for robust and effective drone security measures to protect critical infrastructure and public safety.
