Copenhagen Airport reopened early Tuesday after nearly four hours of suspended operations following reports of drones flying near the facility. Authorities have not confirmed the number or type of drones involved, leaving the source and trajectory of the devices unclear.
Deputy Police Inspector Jakob Hansen told reporters, "It is not known where the drones came from. It is also not known where they have since flown." He added, "We wish we knew where they were at this time, but we are operating based on what the situation is right now."
Operations at the airport resumed around 00:30 local time (23:30 BST), after flights were halted for approximately four hours on Monday evening. Authorities said a "number of measures will be implemented" as part of their investigation but did not provide further details.
Between two to three large drones were reported near Copenhagen Airport, prompting authorities to stop all take-offs and landings temporarily. The airport issued a statement warning of ongoing delays and cancellations, urging passengers to confirm their flight status with airlines.
When asked whether the drones could have been of Russian origin, Hansen said he could not confirm or deny the claim. Danish police announced that another press conference would be held at 07:00 local time on Tuesday to provide updates.
A Copenhagen Airport spokesperson confirmed that airspace over the facility had been closed at around 20:30 local time (19:30 BST) due to unidentified drones. "No aircraft can take off or land at the airport, and as a result, several flights are being diverted to other airports," the statement said.
Flight-tracking website Flightradar24 reported that at least 35 flights bound for Copenhagen were rerouted during the closure.
Meanwhile, Norwegian authorities reported a similar drone sighting near Oslo Airport on Monday evening.
A spokesperson for the airport told local media outlet nrk that the airspace was closed at 00:00 local time (11:00 BST) due to a "drone observation," with all flights redirected to the nearest airports.
Hansen confirmed that Danish police will work with Norwegian authorities to determine whether the incidents are connected.
