Aalborg, Denmark — Drone incursions disrupted air travel across Denmark this week, forcing the closure of Aalborg airport in the country’s north and raising concerns about the security of critical infrastructure. The shutdown followed reports of unauthorised drones entering the airport’s airspace on Wednesday night, according to local authorities.
The disruption led to the diversion of at least three flights, two of which returned to Copenhagen and another to Karup. Officials confirmed that Aalborg airport, which also functions as a Danish Armed Forces base, was directly affected by the incident.
Multiple Sightings Across Denmark
Drone activity was not limited to Aalborg. Police in Denmark’s southern region confirmed reports near three other airports—Esbjerg, Sønderborg and Skrydstrup. While none of those facilities were closed, authorities said they were monitoring the situation closely and treating it as serious.
North Jutland Police issued a statement acknowledging uncertainty about the scale of the activity.
“We cannot yet comment on the purpose of the drones flying in the area, nor can we say anything about who the actor behind it is,” said chief inspector Jesper Bøjgaard Madsen. “If we get the opportunity, we will take down the drones.”
Officials stressed there was no immediate danger to passengers or nearby residents, but urged the public to avoid the areas affected.
Broader Pattern of Incursions
The latest incidents follow a similar disruption earlier in the week at Copenhagen’s Kastrup airport, where flights were halted for several hours due to drone sightings. Prime Minister Mette Frederiksen described that event as “the most severe attack on Danish infrastructure so far.”
“It says something about the times we live in and what we as a society must be prepared to deal with,” she told reporters, while noting that Russian involvement could not be ruled out. Kremlin spokesman Dmitry Peskov dismissed the suggestion as “unfounded.”
European Security Tensions
The incursions come at a moment of heightened sensitivity across Europe. Several NATO members have reported Russian violations of their airspace in recent weeks. Estonia and Poland both requested consultations with allies following separate incidents, while Romania also reported that Russian drones had crossed into its territory.
In response, NATO issued a statement condemning Russia’s actions as “escalatory” and warned it would use “all necessary military and non-military tools” to defend member states. Secretary General Mark Rutte emphasized that NATO remained a defensive alliance but added, “We are not naive, so we see what is happening.”
Unclear Motives
Despite speculation, Danish police have not confirmed whether the drone sightings are linked to foreign actors, domestic groups, or even potential pranks. The devices were reportedly visible from the ground, but investigators have yet to determine who controlled them or their motive.
The European air traffic control agency announced that Aalborg airport would remain closed to arrivals and departures until 06:00 local time (04:00 GMT) on Thursday.
With multiple incidents unfolding in quick succession, Danish authorities are under mounting pressure to improve counter-drone capabilities and safeguard airspace security.
