Poland said it shot down multiple Russian drones that penetrated its airspace overnight, with debris recovered as far as about 150 miles from the Ukrainian border, prompting sharp warnings from European leaders and renewed concerns about an escalation of the war in Ukraine.
Polish Prime Minister Donald Tusk said at least 19 objects entered Polish airspace on Tuesday night. Local officials found parts near Mniszkow, roughly 82 miles southwest of Warsaw and more than 150 miles from the border with Ukraine, and a downed device was also reported near Olesno, close to Elblag and about 124 miles from the eastern border. Polish authorities said two of the unmanned aerial vehicles flew more than 100 miles into Polish territory.
Polish and international officials described the episode as an unprecedented breach of NATO airspace during the war in Ukraine. "Whether it was intentionally or not, it is absolutely reckless. It is absolutely dangerous," Dutch Prime Minister Mark Rutte said, adding that NATO would not stand by while a member state's airspace was violated. Polish Prime Minister Tusk called the incident "the closest we have been to open conflict since World War Two."
A Polish army official told Reuters the unmanned aircraft were inexpensive Gerbera-model drones, which Moscow has used for reconnaissance or as decoys in Ukraine. Analysts and officials have said cheap, mass-produced UAVs can be used to probe air defenses, measure response times and test radar coverage.
European leaders said the incursion gave insight into NATO's readiness and raised alarm about intent. Estonian Prime Minister Kaja Kallas, speaking in Brussels, said Russian President Vladimir Putin was attempting to test Western responses and described the episode as a "game changer," saying Russia's war was escalating rather than winding down.
German Defense Minister Boris Pistorius told parliament there was no evidence the incursion was accidental. "These drones were very clearly put on this course deliberately," he said. NATO officials and allied governments said the scale and depth of the penetration marked a serious escalation but did not detail any immediate military response beyond intercepting the unmanned systems and raising alert levels.
Moscow and its allies provided competing explanations. The Kremlin declined to comment on the specifics, with spokesman Dmitry Peskov saying Western officials routinely attribute such incidents to Russia "on a daily basis." Belarus, an ally of Russia that borders Poland, suggested the drones were intended to strike targets in Ukraine and veered off course after encountering electronic-warfare measures. Russian media outlets suggested Kyiv might have been responsible in order to galvanize European support.
Kyiv's Center for Countering Disinformation dismissed such reports as disinformation and part of a Russian information campaign to justify attacks on Ukraine.
Polish military personnel collected wreckage and continued investigations into the flight paths and origins of the drones. Officials did not immediately report civilian casualties tied to the incursions, but images and local accounts showed damage to property where fragments landed.
Allied leaders reiterated that NATO would defend member territory. Rutte warned President Putin to "stop violating allied airspace" and said the alliance stood ready to defend "every inch of NATO territory." The incident has intensified diplomatic exchanges in Brussels and other capitals as allies seek to assess the implications for collective defense and deterrence amid the wider conflict in Ukraine.
