In the late evening of September 25, 2025, the airspace over Aalborg Airport in Denmark was closed from 23:40 local time to 00:35 on September 26 due to suspected drone sightings, causing the cancellation and diversion of two flights. The Danish government regards these drone incidents across multiple airports as hybrid attacks intended to spread fear. Justice Minister Peter Hummelgaard labeled the threat as ongoing. Defense Minister Troels Lund Poulsen described the perpetrators as professional actors but said Denmark faced no direct military threat. Danish Prime Minister Mette Frederiksen warned of potential escalation in drone incidents. French President Emmanuel Macron expressed France's full solidarity and willingness to assist Denmark in securing its airspace. Danish media reported the Russian landing ship "Aleksandr Shabalin" was detected near the Danish coast in international waters possibly linked to commanding these drone operations. Denmark plans to acquire new drone detection and neutralization technologies and to propose legislation allowing critical infrastructure operators to shoot down drones to counter these hybrid warfare tactics.
