NATO aircraft intervened following Russian drone incursions into Polish airspace on September 10th, 2025, with the specific timing of the engagement not yet detailed within this reporting window. The nature of the threats prompted swift action from NATO forces, including Polish, Dutch, and Italian aircraft, supported by a multinational tanker. German Patriot systems were on alert. The Ukrainian Air Force also reported the threat of ballistic weapons. NATO confirmed swift and firm action during engagements with potential threats to Allied territory, marking the first instance of NATO planes engaging threats in Allied airspace, according to U.S. Army Col. Martin L. O’Donnell, spokesperson for NATO’s Supreme Headquarters Allied Powers Europe. The Air Force of Ukraine expressed full support for Poland and other NATO allies via X. Slovak Prime Minister Robert Fico stated that the violation is a serious incident that could lead to far-reaching consequences, emphasizing the need to determine if the incursion was intentional or accidental and under whose control the drones were operated. He also noted that NATO countries deployed Patriot and SAMP/T systems to cover Slovakia's needs in return for Slovakia providing Ukraine with air defense systems. Earlier in the reporting window, Ukrainian military channels indicated multiple aerial threats across the country on September 10th, 2025, between 2:32 PM and 2:47 PM UTC, including hostile reconnaissance UAVs over Odesa and rocket threats in the Sumy region. The Air Force of Ukraine also reported "managed aviation bombs with hostile tactical aviation to Sumy region" and "Pull UAV ➡️ in the direction of Lebedin!". Russia's Foreign Ministry has labeled reports of drones in Polish airspace as myths and accused Warsaw of escalating the crisis, a claim contested by Insider.com regarding the range of Russian drones. Senator Lindsey Graham described the violation as "RECKLESS," urging European allies to follow President Trump's lead in increasing pressure on nations supporting Russia's war efforts. Dmitry Medvedev of Russia's Security Council issued a warning to Finland regarding confrontation with Russia. Polish authorities recovered debris, including components of Russian drones and an American AIM-120C-7 air-to-air missile, following overnight incursions. U.S. President Donald Trump was scheduled to speak with Polish President Andrzej Duda about these incursions, and NATO had invoked Article 4 of the North Atlantic Treaty at Poland's request. NATO sources had also reported unidentified objects entering Lithuanian airspace earlier on September 10th, with reconnaissance ongoing and no engagement occurring. The Air Force of Ukraine also reported several UAV groups heading in the direction of Kryvyi Rih, and a user on X, @RepJoeWilson, commented on Russia violating Poland's airspace. A map of drones found in Poland so far today was also shared by @BNODesk.
