Several drones were spotted on Wednesday evening near Aalborg Airport. Traffic to and from the airport was stopped.
On Thursday morning, the country's second-largest airport, Billund, was also forced to close its airspace for an hour. Drones have been reported over at least five Danish airports.
We do not rule out anything when it comes to who is behind, says Peter Hummelgaard at a press conference where he emphasizes that drone technology is very potent and constantly evolving.
In a written comment to Jyllands-Posten the Russian embassy in Copenhagen denies that Russia is behind. Instead, they call the events "a staged provocation".
The National Operational Staff (Nost) is currently manned around the clock, announces National Police Commissioner Thorkild Fogde.
Talks with Rutte
Prime Minister Mette Frederiksen has spoken with NATO Secretary General Mark Rutte about the drone situation.
"We agreed that NATO will work with Denmark on what we can do together to ensure security and safety", she writes on X.
According to Mark Rutte, NATO takes the drone incidents very seriously, reports AFP.
Defense Minister Troels Lund Poulsen said during the morning's press conference that everything indicates that a professional actor is behind the events.
What we have seen now is a systematic operation that took place simultaneously – a hybrid attack that threatens our freedom and security.
The drone activity that caused the police to close Aalborg Airport for a few hours resembled, according to the police, the one that stopped air traffic to and from Copenhagen on Monday.
Several drones reported
During the night, drones were also spotted at the military airbase in Skrydstrup and the airports in Esbjerg and Sønderborg. Early in the morning, Billund Airport was forced to close its airspace for about an hour.
A drone has also been spotted at the Dragon Regiment's barracks in Holstebro during the night, writes the defense in a press release. However, the defense does not want to disclose where drones have been observed near military facilities, citing operational security reasons and the ongoing investigation.
The Danish police have received many tips after Monday's events, when Kastrup in Copenhagen was forced to close due to drone activity. Also, the airport Gardermoen outside Oslo was closed due to suspected drones.
