Two Scandinavian airports temporarily shutter over drone sightingsby Darryl CooteWashington DC (UPI) Sep 22, 2025Two Scandinavian airports shuttered on Monday due to drone sightings, raising concerns about aviation safety in Europe amid Russia's war in Ukraine. Copenhagen Airport, Scandinavia's largest, reopened early Tuesday, though it is warning passengers in a statement that "there will be delays and some cancelled departures." The airport suspended service earlier Monday after "2-3 large drones" were seen flying in the airspace, Copenhagen Police said in a social media statement. Deputy Police Inspector Jakob Hansen told reporters that it wasn't known where the drones came from or where they flew to after entering the airport's airspace. The Eastern Police District said in a statement that two foreign nationals have been arrested "for flying drones within the restricted zone."
