Aalborg Airport forced to close
Danish authorities reported fresh drone sightings on Wednesday night, forcing the closure of Aalborg Airport, which also serves as a military base for Danish F-16 jets. Police confirmed drones were detected near the facility, prompting an immediate shutdown of the airspace. Justice Minister Peter Hummelgaard said drones were also observed over Esbjerg, Sonderborg, and the Fighter Wing Skrydstrup base.
“The goal of this kind of hybrid attack is to create fear and discord,” Hummelgaard stated, adding that the government will introduce new detection measures and draft legislation enabling infrastructure owners to shoot down drones if needed.
Pattern of escalating incidents
The latest events follow earlier drone intrusions that shut down Copenhagen Airport and Oslo Airport earlier this week. Defense Minister Troels Lund Poulsen described the activity as a “systematic operation” consistent with professional actors, calling it a hybrid attack. Although he stopped short of directly blaming Moscow, Poulsen emphasized that NATO could be engaged through Article 4 consultations.
Prime Minister Mette Frederiksen echoed these concerns, labeling the incidents “a serious attack against critical infrastructure.” While she would not rule out Russia’s involvement, the Kremlin rejected the accusations, calling them baseless. The Russian embassy in Denmark went further, suggesting the sightings were “a staged provocation” aimed at escalating regional tensions.
NATO’s involvement and international response
NATO Secretary-General Mark Rutte confirmed he had spoken with Frederiksen, saying the alliance takes the drone incidents “very seriously.” NATO and Denmark are now discussing joint measures to better protect infrastructure. Investigators are also considering whether drones could have been launched from nearby ships.
Danish officials identified three Russian-linked tankers as potential sources: the Astrol 1, Pushpa, and Oslo Carrier 3. Only the Pushpa, flagged to Benin and listed as part of Russia’s “shadow fleet,” was near Aalborg during the latest incidents. The vessel has since been tracked moving southwest toward the English Channel en route to India.
Security concerns at a critical juncture
The drone disruptions underscore growing threats to European infrastructure as NATO faces repeated airspace violations and hybrid tactics. While investigations continue, officials across Denmark and NATO stress the urgency of strengthening defenses against unmanned aerial systems, particularly near sensitive military and transport hubs.
