According to Reuters, several airports and military bases in western Denmark found unknown drone invasions on 24 local time.

The report quoted Danish police sources as saying that due to drone invasion, Billund Airport, the second largest airport in Denmark, was closed for one hour, and Aalborg Airport, which also serves as a civil and military airport, was closed for three hours. The two airports reopened on the morning of 25th local time. In addition, drone activity was also found near Esbjerg Airport, Sundborg Airport, Skriedstrup Air Base (where some of the country's F-16 and F-35 fighter jets are based) and a military facility in Holstebro, all affected locations in Jutland, western Denmark.

"This obviously doesn't seem like a coincidence, but an organized and systematic action. I define it as a hybrid attack," Polson told Reuters. At the same time, he added that Denmark currently faces no direct military threat.

The local resident, Morten Skov, said he saw light flashing on the west side of Aalborg Airport and hanging above the airport. A video provided by Skov showed light sources moving from the airport to the west. The report said it was unclear who was the "backdoors" of the above drone invasions. The Danish police said the drones were operating in a similar pattern to the drone interference at Copenhagen Airport on the night of 22.

In the evening of the 22nd, the Danish capital, Copenhagen, Caesarship International Airport, dropped about four hours from the flight due to the discovery of several unknown drones suspended. Early on the morning of the 23rd, Oslo Gallemoen International Airport, Norway, was also closed for about three hours due to the discovery of unknown drones. Danish Prime Minister Fredericksson said on the 23rd that the drone interference at Copenhagen Airport on the night of the 22nd was a "serious attack" on Danish critical infrastructure. In addition, Russia's allegations of possible involvement in Danish and Norwegian drone incidents, Russian President Press Secretary Peskov said on the 23rd that if the West made such unfounded allegations every time, such statements would eventually no longer be able to attract attention.
