Poland said it shot down at least three unmanned aerial vehicles after detecting 19 violations of its airspace overnight, prompting Prime Minister Donald Tusk to invoke NATO’s Article 4 and draw international warnings about an escalation that some leaders described as bringing Europe closer to the risk of open conflict than at any time since World War II.
Polish authorities and NATO allies said the drones originated from Russian-controlled areas and damaged civilian property in eastern Poland. Tusk described the incident as an unprecedented provocation and said Poland had worked with allies to counter the incursion. On social media, former U.S. president Donald Trump reacted to the reports with the message "Here we go!" and asked, "What's with Russia violating Poland's airspace with drones?".
Poland said the drones penetrated its airspace from the direction of Ukraine and that at least three were shot down. Local officials reported a damaged house and a vehicle; the home, according to local media, belonged to an elderly couple who were reportedly outside tending animals when one drone struck. Polish Defence Minister Boris Pistorius told lawmakers the drones appeared to be "suitably armed" and were "clearly set on this course," arguing there was no reason to view the flights as navigational error.
Warsaw’s decision to trigger Article 4 of the North Atlantic Treaty — a mechanism allowing any member to request consultations when it perceives a threat to its territorial integrity, political independence or security — led NATO’s North Atlantic Council to change the format of its weekly meeting to address the incident. Tusk called the move the eighth invocation of Article 4 in the alliance’s history.
Russia denied responsibility for an attack on Polish territory. The Russian defence ministry said it was ready to hold consultations with the Polish defence ministry over what it called an "alleged" incursion and contended that the drones that reportedly crossed the border had a range of no more than 700 kilometres and that its forces had "achieved all its targets" in the operation. The Russian foreign ministry accused Warsaw of spreading "myths" to escalate the war in Ukraine, and the Russian embassy in Warsaw said Poland had failed to present proof of Russian origin for the objects.
Ukrainian President Volodymyr Zelensky called the intrusion a "dangerous precedent" and said it was "no accident," urging a firm NATO response. Poland’s foreign minister, Radoslaw Sikorski, said the scale of the breaches — 19 in total — made a technical malfunction implausible, and described the incident as an attack on NATO and European Union territory.
European and NATO members responded with sharp statements. German Chancellor Friedrich Merz condemned the drone flights as a "reckless action" that endangered lives and threatened NATO territory. Germany’s defence minister and other officials said the pattern of the flights suggested deliberate direction toward Polish airspace rather than navigational error. Lithuanian and other Baltic officials warned the incursions risked dragging the alliance into reciprocal uses of military force.
Allied capital responses included statements calling for de-escalation while underscoring readiness to defend NATO territory. Canada’s prime minister described the incursion as "reckless and escalatory" and said Ottawa was coordinating closely with allies to increase pressure on Russian leadership. In London, Opposition Leader Sir Keir Starmer called the violation "egregious and unprecedented," offering support to Poland.
NATO officials have not publicly detailed any military response beyond the consultations under Article 4. The alliance’s political meetings can lead to joint decisions or coordinated actions, but Article 4 does not automatically trigger the collective-defense clause, Article 5. Diplomats said the consultations are intended to assess the facts, share intelligence among allies and determine appropriate collective steps.
Poland has said it remains in close communication with NATO partners as investigators and military personnel examine wreckage and flight paths. The incident adds to mounting tensions on NATO’s eastern flank amid Russia’s war in Ukraine, prompting allies to weigh how to deter further incursions while avoiding direct military confrontation.
Further developments are expected as NATO’s council meets and Polish and allied officials continue investigations into the origin, payload and flight intentions of the unmanned aerial vehicles. Moscow’s offer of talks, coupled with its denial of responsibility, leaves contested facts at the center of the consultations and heightens diplomatic stakes for the alliance and its partners.
