Copenhagen Airport (CPH) will remain closed until at least 0700 UTC on September 23rd, 2025, due to ongoing drone activity, with approximately 50 flights canceled and 50 diverted as of the past 27 minutes. The situation has expanded to Oslo Gardermoen Airport in Norway, which is also reporting the presence of unidentified drones in its airspace. Police continue to monitor the situation around Copenhagen Airport, with an increased presence. Eurocontrol confirmed that Copenhagen Airport's closure will extend through 0700 UTC, with an additional 20 flights anticipated to divert in the coming hours. The previous report indicated that the airport's airspace closure began around 8:26 PM local time on September 22nd, 2025, following sightings of multiple large drones, which police stated were not hobby drones. A SAS passenger plane had made an emergency landing due to low fuel during the initial disruption. In parallel, Norwegian authorities reported the arrest of two foreign nationals in Oslo on Monday night for illegally operating a drone near Akershus Fortress, which was recording sensitive military sites. Separately, reports emerged of unusually heavy GPS jamming and spoofing around Kaliningrad. The Global Sumud Flotilla, comprising nearly 40 vessels at sea, also reported multiple drones following it. The extended closure at Copenhagen Airport follows an earlier NOTAM indicating operations would be suspended until an estimated 5:00 AM UTC on September 23rd, 2025. Sweden's Defense Minister has reiterated the country's readiness to use force to protect its airspace. Unconfirmed reports of drone activity over Stockholm's Arlanda Airport were also noted in previous reporting.
