Overview

• Both airports have reopened after multi‑hour shutdowns, with about 109 flights canceled and 51 diverted in Copenhagen and 19 canceled and 11 diverted in Oslo, affecting roughly 20,000 passengers.
• Danish police said they did not attempt to shoot down the large drones due to safety risks near busy runways and housing, noting the devices approached from different directions and then vanished without recovery.
• Danish and Norwegian police, militaries and intelligence services are jointly investigating, as Denmark’s PET warns of a significant sabotage threat and Prime Minister Mette Frederiksen calls it the most serious attack on national critical infrastructure.
• NATO convened in Brussels and urged Russia to cease escalation following recent airspace violations reported by Estonia, Poland and Romania, while Secretary‑General Mark Rutte said it is too early to attribute the Copenhagen incident.
• The Kremlin denied any role, and Norway disclosed three separate Russian airspace violations this year, underscoring regional tensions as attribution for the latest drone flights remains unproven.
