Aalborg Airport in northern Denmark was forced to close on Wednesday following the detection of drones in its airspace, authorities have confirmed. The incident led to the halting of incoming and departing flights, with four services being affected.

Nordjyllands Police stated on X (formerly Twitter) that drones had been observed near the airport, prompting the closure of the airspace. Police are present at the scene and are conducting an investigation.

An airport spokesperson did not specify the number of drones sighted. Among the affected flights were two operated by Scandinavian Airlines (SAS), one by Norwegian, and one by KLM. These flights were diverted, with two SAS planes returning to Copenhagen.

This is the second time in three days that a Danish airport has been temporarily shut down due to drone activity. On Monday, Copenhagen Airport, Denmark's largest, experienced similar disruptions. Danish Prime Minister Mette Frederiksen described the earlier incident as potentially the “most serious attack to date on Danish critical infrastructure” and did not rule out any possibilities regarding who was behind it. She later stated she “cannot deny” that drones seen over the airport were flown by Russia.

Russia, through Kremlin spokesman Dmitri Peskov, has denied involvement, stating that unfounded accusations detract from their seriousness.

The events in Denmark follow a series of disruptions at European airports. Last week, airports in Berlin, Brussels, and London Heathrow experienced cyberattacks that impacted services and led to flight cancellations. The perpetrators of these cyberattacks remain unidentified.

Authorities in Norway also temporarily closed the airspace at Oslo Airport for three hours due to a drone sighting. Norwegian and Danish officials are in close contact regarding the incidents, though no connection has been established by investigators yet.

Eurocontrol, the European air traffic control agency, indicated that arrivals and departures at Aalborg Airport were scheduled to resume at a “zero rate” until 04:00 GMT/UTC on Thursday.
