The Danish national police said that the drones exhibited a similar pattern to those that had disrupted flights at Copenhagen Airport for four hours just days earlier. They added that the country’s armed forces were also impacted, as Aalborg Airport, which was affected, serves as a military base.
Earlier this week, on Tuesday, Denmark said that the incident at the Copenhagen Airport was the most serious attack on its infrastructure yet, connecting the drone sightings to previous Russian incursions and disruptions across Europe.
Northern Jutland police have said that "more than one drone" was spotted in its airspace and that they were flying with the lights on. “It is too early to say what the goal of the drones is and who is the actor behind it,” a police official said.
Copenhagen disruption
According to Eurocontrol, at least 50 flights were cancelled, while more than 50 others were diverted to airports in Denmark and southern Sweden, including Billund, Aarhus, Malmö and Gothenburg. Flight-tracking site Flightradar24 reported that at least 35 planes bound for Copenhagen had to change course.
Minutes after the incident in Denmark, drones were also reported over parts of Norway and Sweden. Norwegian police confirmed a drone sighting near Oslo Airport, forcing air traffic onto a single runway “for safety reasons.”
Nato warns Russia
Nato said it was "too early to say" whether Russia was responsible, but warned Moscow to stop an "escalatory" pattern of airspace violations along its eastern flank.
Ukrainian President Volodymyr Zelenskyy denounced what he called a Russian violation of Denmark's airspace in a message on X.
Danish intelligence said the Scandinavian country was facing a "high threat of sabotage".
"Someone may not necessarily want to attack us, but rather stress us out and see how we react," said Flemming Drejer, director of operations at Denmark's intelligence service PET.
