Overview

• Copenhagen Airport shut after sightings of two to three large drones around 20:30 local time and reopened near 00:20, with delays and cancellations continuing.
• The Copenhagen disruption diverted flights to other Danish airports and to Gothenburg and Malmö, with airport officials reporting 31 diversions and roughly 100 delayed or canceled flights affecting about 20,000 passengers.
• Oslo Airport temporarily closed early Tuesday following a separate drone sighting, redirecting inbound flights to the nearest airports as police opened an investigation.
• Oslo police earlier arrested two foreign nationals over a drone flown above restricted Akershus Fortress, an incident authorities say is not connected to the airport cases.
• Danish police described the Copenhagen activity as a “hybrid operation” carried out by a trained operator, are coordinating with Oslo, and report no suspects or verified attribution despite public accusations by Ukraine’s president.
