Denmark’s Prime Minister Mette Frederiksen has labeled the drone incursion that disrupted Copenhagen Airport on Monday night as “the most severe attack on Danish infrastructure so far.” The incident, which forced the closure of Kastrup Airport for several hours, was described as an attempt to “disrupt, create unrest, and test the limits” of Denmark’s defenses. Frederiksen drew parallels between this event and recent Russian drone incursions in Poland, Romania, and Estonia, suggesting a broader pattern of destabilization. While Kremlin spokesman Dmitry Peskov dismissed the allegations as “unfounded,” Danish intelligence warned of a “high threat of sabotage.” Flemming Drejer, director of operations at Denmark’s intelligence service PET, noted that the motive may have been to “stress us out and see how we react.” Around 20,000 passengers were affected by the airport closure, which resumed operations after midnight. Danish police described the drone operators as a “capable actor” but have yet to identify their origin. In Norway, Oslo Airport also faced a temporary closure due to suspected drone activity, with 14 flights diverted. Norwegian Prime Minister Jonas Gahr Store condemned Russia’s repeated airspace violations in 2025, emphasizing that such actions are “not acceptable.” The incidents have heightened tensions in Europe, with NATO bolstering its eastern flank by deploying troops and fighter jets from member states, including the UK, France, Germany, and Denmark. The alliance has also warned of a “wider pattern of increasingly irresponsible Russian behavior” following recent incursions into Poland, Romania, and Estonia. As the conflict in Ukraine continues, NATO members like Poland and Sweden have vowed to shoot down any unauthorized objects in their airspace, underscoring the growing security challenges in the region.
