On the night of September 9, Stockholm’s Arlanda Airport temporarily suspended flights due to the presence of drones in the area, according to a report from Reuters citing local police.
Arlanda Airport is the largest airport in Sweden.
The drone sightings occurred around 11 p.m. local time, forcing a halt in both departures and arrivals until 1:30 a.m.
Police are now investigating the incident as a possible act of sabotage.
"We suspect this was a deliberate act, but we cannot yet say what the motive was," said police spokesman Daniel Vikdal to SVT Nyheter. He noted that due to the sensitivity of the investigation, details about the types of drones involved and who may have seen them are being withheld.
Cecilia Begström, spokeswoman for the Swedish Civil Aviation Authority, confirmed that four drones were detected over the airport, though their model and origin remain unknown. It is also unclear whether the drones were neutralized or left the area on their own.
The drone-related disruption comes a day after a Russian drone crashed in Latvia, which had flown in from Belarus. This incident is the first known instance of a Russian drone entering Latvian territory, and authorities are working closely with NATO to investigate.
