Aalborg Airport in Denmark was closed Thursday morning due to drone activity, following a similar incident at Copenhagen Airport earlier this week. The drones, sighted with lights on, caused a disruption to both commercial and military flights. Authorities are investigating, but the drones' type, origin, and purpose remain unknown. This incident follows other recent drone-related airspace closures in Norway and raises further European security concerns. Three flights were diverted.
