After air traffic was blocked at Copenhagen and Oslo airports between Monday, September 22nd and Tuesday, September 23rd, due to the threat of drones (see AVIONEWS), last night the Danish airport of Aalborg, also used as a military base, halted its operations -now resumed- again due to the presence of unknown unmanned remote-controlled aircraft in its airspace at approximately 9:44 PM, according to regional police. Initial speculation suggests Russian involvement, but Danish defense minister Troels Lund Poulsen has stated that there is no evidence yet and that, in any case, the drones were operated by a professional. Kremlin spokesman Dmitry Peskov has called the accusations "unfounded". The number of drones in flight and their origin are still unclear, although the defense minister has emphasized that "they don't come from very far away".

As reported by Flightradar, the last takeoff from Aalborg occurred at 9:19 PM local time; two flights were diverted to Copenhagen and one to Karup. One incoming flight and two outgoing flights were cancelled. Three other smaller airports in the south of the country -Esbjerg, Sønderborg, and Skrydstrup- also recorded drones flying over them, but continued to operate. The Uavs (unmanned aerial vehicles) were not shot down for the safety of the population, explained Defence Minister Michael Hyldgaard.

A meeting convened by European commissioner for defense and space Andrius Kubilius is scheduled for tomorrow between Estonia, Latvia, Finland, Lithuania, Poland, Romania, and Bulgaria, along with Ukraine. The aim is to assess how to build a "drone wall" to protect the European Union's borders, as requested by Commission president Ursula von der Leyen in her State of the Union address in early September (see AVIONEWS).
