Denmark's Aalborg airport reopens after brief closure due to suspected drone activity

The airspace over Denmark's Aalborg Airport was reopened early on Friday after a closure for the second night in a row due to suspected drone activity, police said.

"The airspace over Aalborg Airport has been reopened on Friday at 00:35 (2235 GMT) after having been shut down due to suspicion of drone activity," police said in a post on social media X.

The airspace over Aalborg Airport was closed nearly an hour earlier at 11:40 p.m. local time (2140 GMT) on Thursday after a suspected drone sighting in the area, police told news agency Ritzau.

On the previous evening, Aalborg airport, used for commercial and military flights, was closed for about three hours due to drones in its airspace, just days after the country's main Copenhagen airport was shut over drone sightings that raised European security concerns.

Denmark's defence minister said on Thursday the nightly drone sorties were hybrid attacks, combining military and covert tactics, and were aimed at spreading fear.

Danish officials said it was still unclear who was behind the incidents, and Denmark had not yet decided whether to invoke NATO's Article 4, which allows members to request consultations over any security concerns.
