The drone incursion that stopped flights at Copenhagen airport on Monday night was 'the most severe attack on Danish infrastructure so far,' Denmark's Prime Minister Mette Frederiksen said. Kastrup airport in Copenhagen was forced to shut for several hours following the sighting of several drones. Frederiksen remarked, 'It says something about the times we live in and what we as a society must be prepared to deal with.' She indicated that Russian involvement could not be ruled out, although Kremlin spokesman Dmitry Peskov dismissed the allegations as 'unfounded.' The Danish PM linked the drone incursions to recent similar events in Poland and Romania, suggesting the motive was to disrupt and test limits. Danish intelligence reflected this tune, citing a high threat of sabotage. Notably, around 20,000 passengers faced disruptions due to the airport's closure. Earlier reports from Danish police indicated the drones were operated by a 'capable actor.' In context of the rising tensions, Norwegian authorities also reported possible drone sightings at Oslo airport, which had to implement temporary closures amid similar fears about security.
