Drone Incursions Cause Major Disruption at Copenhagen and Oslo Airports

On the night of September 22, 2025, Copenhagen Airport, the largest in Scandinavia, was forced to shut down for nearly four hours due to sightings of two to three large unidentified drones. The incident, which also affected Oslo Airport in Norway, resulted in significant flight disruptions, with approximately 35 flights diverted and thousands of passengers stranded. Danish authorities have characterized the drone incursions as a serious attack on critical infrastructure, raising concerns about potential links to recent Russian military activities in the region.

Danish Prime Minister Mette Frederiksen described the drone activity as “the most serious attack on Danish critical infrastructure to date,” emphasizing the need for heightened vigilance in light of recent airspace violations by Russian drones in Poland, Romania, and Estonia. NATO Secretary-General Mark Rutte stated it was “too early to say” whether Russia was involved, while Danish police chief superintendent Jens Jespersen noted that the drones were operated by a “capable actor,” suggesting a level of sophistication beyond casual hobbyist use.

Frederiksen further stated, “I cannot rule out in any way that it is Russia,” linking the incident to a broader pattern of Russian provocations against NATO member states. Meanwhile, Kremlin spokesperson Dmitry Peskov dismissed the allegations as “unfounded accusations,” asserting that Russia had no involvement in the drone incidents.

Ukrainian President Volodymyr Zelensky has publicly attributed the drone incursions to Russian actions, warning that without a resolute response from NATO allies, such provocations will continue. European Commission spokesperson Anitta Hipper echoed this sentiment, stating that the incidents reflect a clear pattern of Russian aggression aimed at testing European defenses. Critics argue that NATO's response to these incursions has been insufficient, potentially emboldening further Russian provocations.

The drone incursions highlight vulnerabilities in European airspace security, particularly as tensions with Russia escalate. Experts warn that such hybrid threats—combining drone activity with cyberattacks—pose significant risks to critical infrastructure across Europe. The recent incidents have prompted discussions among EU members about establishing a “drone wall” to enhance airspace security, involving countries such as Bulgaria, Estonia, Finland, Latvia, Lithuania, Poland, and Romania.

While Danish authorities have not confirmed the origin of the drones, speculation about their potential launch points—whether from land or maritime sources—remains. The lack of definitive evidence linking the incursions to Russian operations leaves room for ambiguity, with some officials suggesting the possibility of a coordinated effort to test NATO's response capabilities.

In response to the drone incidents, Denmark will participate in discussions with other EU nations regarding enhanced airspace security measures. Additionally, NATO is set to hold further meetings to address the ongoing threat posed by Russian military activities in Eastern Europe, including the recent violations of Estonian airspace by Russian fighter jets.
