Poland announced it shot down multiple drones that violated its airspace late Tuesday night, and Prime Minister Donald Tusk asked NATO to open consultations under Article 4 of the alliance's treaty, calling the episode the most dangerous security situation since World War II.
Tusk told Poland's parliament on Wednesday that 19 drones had crossed into Polish airspace as Russia continued launching airstrikes on neighboring Ukraine, and that any drones "that posed a direct threat" had been engaged. He said the incident marked the first time a NATO member had opened fire during the Ukraine war, and warned that the possibility of a large conflict was "closer than at any time since World War II." He added that "there is no reason to claim that we are in a state of war... but the situation is significantly more dangerous than all previous ones."
NATO Secretary General Mark Rutte said the violations were not isolated and that allied air defenses successfully "ensured the defense of NATO territory." Rutte said a number of countries contributed to the operational response alongside Polish F-16 jets, including military equipment from Italy, Germany and the Netherlands, and he expressed solidarity with Poland and its allies. "Allies are resolved to defend every inch of allied territory… This only reinforces the importance of NATO and the path to which allies agreed at our summit in The Hague earlier this year," Rutte said, urging increased investment in defense and defense production.
Responding to Poland's account, Russian Charge d'Affaires Andrei Ordash said he had been summoned by the Polish foreign ministry and that Warsaw provided no evidence linking the drones to Russia, according to state news agency RIA Novosti. The Russian Ministry of Defense posted a statement on Telegram saying there were "no targets planned for destruction on Polish territory" and asserting that "the maximum flight range of the Russian UAVs used in the strike, which allegedly crossed the border with Poland, does not exceed 700 km." The ministry said it was "ready to hold consultations with the Polish Ministry of Defense on this topic." Time has reached out to Russia's Ministry of Defense for further comment.
Ukrainian President Volodymyr Zelensky said Ukrainian forces informed Poland of movement by Russian drones and described broader drone activity. "In total, at least several dozen Russian drones were moving along the border of Ukraine and Belarus and across western regions of Ukraine, approaching targets on Ukrainian territory and, apparently, on Polish territory," he said, and offered to expand cooperation with allies on information sharing and aerial defenses.
European and Western leaders condemned the incursions. European Union High Representative Kaja Kallas called the episode "the most serious European airspace violation by Russia since the war began." U.K. Prime Minister Sir Keir Starmer described the incident as "egregious and barbaric" and said Britain would continue to work with partners to pressure Russia until a "just and lasting peace" is achieved.
Tusk's Article 4 request invokes a consultation mechanism that obliges NATO members to meet and discuss a perceived threat to any member's territorial integrity, political independence or security. The move stops short of invoking Article 5, the treaty's collective defense clause, but signals the heightened alarm in Warsaw and among NATO capitals.
The incident follows a year-and-a-half-long Russian campaign against Ukraine that has repeatedly targeted civilian infrastructure and drawn sustained Western support for Kyiv. NATO officials and allied leaders said the border incursions demonstrated the increasingly fluid and hazardous security environment in Europe and underscored the alliance's commitments outlined at its recent summit in The Hague.
The events also follow a meeting of the "Coalition of the Willing" in Paris last week in which 26 countries committed to deploying troops to Ukraine as a reassurance force once the conflict ends. Allied officials have said they are stepping up cooperation on air defenses and intelligence sharing to better detect and counter unmanned aerial systems.
Polish authorities have not released detailed forensic evidence publicly tying the drones' origin to Russia, and Moscow's denials underscore the potential for competing narratives as NATO and Warsaw complete their assessments. An ongoing full assessment of the incident was under way Wednesday, NATO officials said, as allied militaries and diplomats sought to establish the facts and determine next steps.
The breach and Poland's response have heightened tensions across the alliance and prompted renewed calls from some leaders for accelerated defense spending and production to ensure NATO members have the capabilities to deter and defend against cross-border threats. For now, allied leaders emphasized a mix of military readiness and diplomatic engagement as consultations under Article 4 proceed.
