Copenhagen Airport has resumed normal operations as of 7:00 AM UTC on September 23rd, 2025, following significant disruptions caused by unidentified drone activity that began on September 22nd. The airport had been closed for several hours, resulting in 51 diverted flights and 109 cancelled flights during the period from 6:05 AM to 7:05 AM UTC on September 23rd. Danish police are investigating the incidents, with preliminary findings suggesting the drones may have been launched from a ship at sea, with one German coast guard ship reportedly observing the area. In a statement this morning, Danish Minister of Defence Troels Lund Poulsen described the drone activity against Copenhagen Airport as "deeply serious and worrying," emphasizing the need for Denmark to enhance its security capabilities. He noted that parallels could be drawn to other events in Europe and stressed the necessity for the country to "get into a completely different gear when it comes to Denmark's security" to protect itself in an uncertain world. The investigation into the source and intent of the drone activity is ongoing. This period of disruption follows earlier incidents and warnings. Ukrainian President Volodymyr Zelenskyy had previously cautioned in New York about potential Russian airspace provocations in response to Western moderation, linking his remarks to earlier drone sightings over Copenhagen. In related events on September 22nd, two foreign nationals were arrested in Oslo for illegally operating a drone near Akershus Fortress, and a drone was seized near Oslo Airport.
