On September 22-23, 2025, drones breached Copenhagen and Oslo airports, causing temporary closures and grounding flights; EU officials suspect Russia is testing European borders amid ongoing investigations.
During the night spanning September 22 to 23, 2025, two unidentified drones flew over and threatened the airports in Copenhagen, Denmark, and Oslo, Norway, leading both to suspend operations temporarily and ground over 50 aircraft. Copenhagen Airport was closed from 8:30 p.m. until 1 a.m., while Oslo Airport halted operations for several hours from 00:30. The drones were not shot down but disappeared on their own, with police describing the perpetrators as competent. Initial analyses indicate the drones were launched from boats at sea and did not enter via the Baltic Sea airspace. These incidents are part of a recent pattern of drone incursions into EU airspace, notably starting with about twenty drones over Polish skies earlier in September. The European Commission spokesperson said Russia is likely testing EU borders, although investigations are ongoing. Danish Prime Minister linked these events to other hostile activities in the region such as airspace violations and cyberattacks. In response, the EU is considering funding a "drone wall" defense system involving key bordering countries and Ukraine, but implementation discussions continue. The incidents have heightened tensions and elicited firm political statements from Polish and Danish officials warning of defensive actions against further incursions.
Confidence: High
Classified as aggressor event due to clear references to drone incursions targeting EU allied airspace with an attribution by EU officials suspecting Russia of testing borders. Classified as defense preparation event because EU and member states are planning to establish a 'drone wall' defense system to deter such threats, indicating proactive defensive measures.
