Copenhagen Airport has resumed normal operations as of 7:00 AM UTC on September 23rd, 2025, following disruptions caused by unidentified drone activity. Danish police described the incident as an "attack" and are investigating, with preliminary findings suggesting the drones were launched from a ship at sea by "skilled operators," according to a statement this morning. The airport closure between 6:05 AM and 7:05 AM UTC resulted in 51 diverted and 109 cancelled flights. Neither the drones nor their controllers were located, though eyewitnesses report seeing objects in the sky. Denmark and Norway will cooperate to determine if the incidents in Oslo and Copenhagen are connected, Danish police stated today. The drone activity was characterized as "deeply serious and worrying" by Danish Minister of Defence Troels Lund Poulsen, who emphasized Denmark's need to enhance security capabilities. This follows earlier drone sightings near Oslo airports and arrests in Oslo on September 22nd of two foreign nationals for illegally operating a drone near Akershus Fortress, with another drone seized near Oslo Airport. Danish Prime Minister Mette Frederiksen previously called the drone incident a "violent attack" and stated it must be viewed within the context of broader European tensions, without ruling out Russian involvement. Denmark activated its national crisis coordination team to level 1 for enhanced monitoring and preparedness. Malmö residents also reported multiple drone alarms on the nights of September 22nd and 23rd, though police could not confirm any sightings. In a separate but potentially related development, footage of a drone flying very low over Copenhagen Airport was shared online. Separately, an incident involving an object landing in the Reutov district of Moscow region, east of the Kremlin, was also reported today.
