COPENHAGEN: Another suspected drone incursion forced the temporary closure of Aalborg Airport in northern Denmark late Thursday, amid growing concerns over what Danish authorities are now calling “hybrid attacks” targeting the country’s critical infrastructure.

Danish police confirmed that airspace over Aalborg was shut down for nearly an hour after reports of drone activity, before being safely reopened. This latest scare adds to a series of drone sightings over the past week that disrupted operations at multiple airports — including Billund, Esbjerg, and Sønderborg — as well as the Skrydstrup air base.

Danish Prime Minister Mette Frederiksen has warned that the country is likely facing a campaign of hybrid warfare designed to spread fear and sow division. “There is one main country that poses a threat to Europe’s security, and it is Russia,” she said bluntly, linking the incidents to broader geopolitical tensions.

Justice Minister Peter Hummelgaard echoed the concern, stating that the intent behind the drone activity appeared to be “to spread fear, create division, and frighten us.” Meanwhile, Defence Minister Troels Lund Poulsen said the repeated incursions suggested “the work of a professional actor”, though he noted that the incidents did not pose a direct military threat.

Russia has denied any involvement, calling the allegations a “staged provocation.”

Danish intelligence and security agencies continue to investigate the incidents, as the government ramps up security measures at airports and other sensitive sites.
