On the evening of 26 September 2025, Danish authorities observed one or two drones flying for multiple hours over Karup, Denmark's largest military base hosting all Air Force helicopters, air defense, training, and the general staff command. The incident was first reported publicly the next day. The civilian airport Midtjylland that shares runways with Karup temporarily closed as a precaution but had no scheduled flights at that time. The investigation by Danish police and military has not yet identified the origin of the drones. Similar recent drone sightings occurred near Norway's largest air base Örland and in northern Germany's Schleswig-Holstein. The Danish government termed the drone flights a 'hybrid attack', attributing the activity to a professional actor aiming to cause unrest. Russia denied involvement. These incidents have intensified political calls within the EU for improved drone defense and legislative reforms, with Germany's Interior Minister Alexander Dobrindt announcing plans to better regulate drone countermeasures. The events reflect increased hybrid warfare threats targeting NATO airspace and infrastructure in the Baltic-Nordic region.
