No evidence drones shut down Copenhagen Airport: police
Danish police say they have found no evidence to prove that the flying objects that closed Copenhagen Airport last year were drones, following a nine-month investigation into what was seen at the time as a possible attack.
Copenhagen Airport suspended flights on September 22 after objects were seen in the airspace.
In the following days, the Danish air force’s main fighter base and other airports suspended operations following similar incidents.
“We cannot confirm that there is drone activity in and around the airport. We also cannot rule out the possibility of … drone activity,” Police Chief Inspector Soren Thomassen told reporters.
The official added that no suspects were identified and the investigation was closed.
Last year’s events have sparked alarm among members of the NATO military alliance as they are seen as part of an increasingly suspected pattern of hybrid warfare targeting critical infrastructure in the North and Baltic region.
At the time, Prime Minister Mette Frederiksen described the incidents as the most serious hybrid attacks to date on the country’s critical infrastructure but refrained from directly attributing responsibility.
Russia, which has regularly denied NATO accusations of carrying out drone and online attacks in Europe, especially since its invasion of Ukraine, said at the time that it had nothing to do with the events in Denmark.
Justice Minister Nicolai Wammen said on Thursday that the government and authorities were taking the situation very seriously due to ongoing cyber attacks on European airports, airspace restrictions in Poland and the upcoming European Union summit in Copenhagen.
“It is part of the nature of hybrid warfare that the enemy does not reveal himself, and so there may be situations in the future where it is far from certain that we will be able to get answers to all our questions,” he added.
In a separate report published last week, the Danish Armed Forces concluded that drones flew over Danish military installations several times in September 2025, based on observations and technical information reported by soldiers.
The armed forces said last week it was the police’s responsibility to investigate and prosecute any criminal activity.
