”The police take all reports seriously, and advise that you document time and place as well as possible, and describe the drone in detail, preferably with a photo or video", writes Denmark's national police.
Some of the alarms have turned out to be false – for example, Billund Airport was closed for a while on Friday morning, but the "drone" turned out to be stars in the sky.
On Thursday evening, the airspace over Aalborg Airport was also closed after reports of suspected drones.
These are just the latest incidents in a long line. The suspicions have been directed at Russia, and Denmark's Prime Minister Mette Frederiksen has formulated it as her country "having been subjected to a hybrid war in recent days”.
At a press conference on Friday afternoon, however, Henrik Brodersen, head of the agency Styrelsen for Samfundssikkerhed, emphasizes that the situation is not considered a military threat.
It is important to say that there is no reason for people to feel insecure.
Denmark's government has no plans to activate NATO's Article 4, says Foreign Minister Lars Løkke Rasmussen.
Article 4 means that the defense alliance's members must consult urgently when a member country feels threatened.
