On October 3, 2025, unidentified drones were sighted near Munich Airport, Germany, causing the temporary suspension of flights, impacting nearly 3,000 passengers, and prompting a closure starting at 10:18 p.m. local time. Flights resumed early the next morning with passengers rebooked or rescheduled. Simultaneously, Belgian officials reported multiple drone sightings over the Elsenborn military base in eastern Belgium near the German-Belgian border. German police identified 15 drones around Düren, approximately 20 miles from the border. Belgian Defense Ministry stated it was examining the drone activity, with the number of drones still under investigation. Authorities have not confirmed the drones' origin, but widespread suspicion in European capitals points to Russian attempts to probe NATO's security posture, amid ongoing Russian airspace violations across Poland, Romania, Estonia, and recent Danish incidents. Danish Prime Minister Mette Frederiksen emphasized the need for a strong European response to these threats.
