Flights delayed at Danish airport due to drones

Denmark’s Aalborg airport, used for commercial and military flights, was closed due to drones in its airspace, two days after the country’s main Copenhagen airport was shut over drone sightings that raised European security concerns, Reuters writes.

Danish national police said the drones followed a similar pattern to the ones that had halted flights at Copenhagen airport for four hours a few days earlier. The closure of Aalborg airport also affected Denmark’s armed forces because it is used as a military base, police added.

Denmark said on Tuesday the incident at Copenhagen airport was the most serious attack yet on its critical infrastructure and linked it to a series of suspected Russian drone incursions and other disruptions across Europe. Authorities in Norway also shut the airspace at Oslo airport for three hours on Monday evening after a drone was seen.

Danish police told reporters “more than one drone” had been sighted near Aalborg airport and they were flying with lights on. The drones were first seen at about 9:44 p.m. on Wednesday, according to police, and remained in the airspace until 12:54 a.m. on Thursday.

Police said they were investigating further on site and cooperating with the national intelligence service and the armed forces, as well as authorities in other countries.

There is no danger to passengers at Aalborg airport or residents in the area, police said.
