Poland downs Russian drones in “act of aggression” on borderline of triggering NATO’s Article 5

Poland has confirmed that its airspace was repeatedly violated by Russian drones overnight, prompting the country’s armed forces to launch a large-scale military operation that resulted in the downing of several aerial targets. The incident marks the first time Polish forces have shot down unmanned aircraft that crossed from the Ukrainian border, creating what officials described as an “act of aggression” and sparking NATO-level consultations.

An attack on a NATO member could activate Article 5 of the Alliance, potentially leading to unpredictable consequences involving Russia, the world’s foremost nuclear power.

The Operational Command of the Polish Armed Forces reported at around 4 a.m. CET that “our airspace was repeatedly violated by unmanned objects” during Russia’s latest wave of strikes against Ukraine. In response, the military scrambled both Polish and allied fighter jets, which used live weapons to neutralise the drones. “An operation to identify and neutralise these objects is underway… weapons were used, services are working to identify the location of the downed targets,” the command said.

Prime Minister Donald Tusk quickly addressed the public, underscoring the gravity of the situation. “An operation related to numerous violations of Polish airspace is underway. The military has used weapons against targets. I am in constant contact with the president and the minister of defence. I received a direct report from the operational commander,” Tusk wrote on social media. Citizens in the Masovian, Podlaskie and Lublin regions were urged to stay indoors due to the heightened risk.

Defence Minister Władysław Kosiniak-Kamysz also confirmed that Polish and allied jets had fired on “hostile objects” and stressed that Warsaw was in permanent contact with NATO command. “The aircraft used weapons against enemy objects,” he said. His message was clear: Poland sees the drone incursions not as isolated incidents but as a hostile act requiring a coordinated alliance response.

The unprecedented airspace breach triggered the temporary closure of four Polish airports, including Warsaw’s Chopin hub, Rzeszów and Lublin, after the US Federal Aviation Administration issued a notice citing “unplanned military activity to ensure national security”. Thousands of passengers and airlines were left stranded as flights were rerouted, delayed or cancelled. Chopin Airport confirmed that while the terminal remained open, all departures and arrivals were suspended for hours.

Poland has in the past dispatched jets to monitor its skies during massive Russian bombardments of Ukraine. But this is the first confirmed case of multiple drones crossing the Polish border en masse and the first time Warsaw has ordered them to be shot down. The Operational Command described the scale of the incursion as “unprecedented”, adding that several of the objects had already been recovered.

The Polish military denounced the episode as a direct threat. “Following today’s attack by the Russian Federation on Ukrainian territory, there was an unprecedented violation of Polish airspace by drone-type objects. This is an act of aggression that created a real threat to the safety of our citizens,” the command said.

Putin “tests the West”

Kyiv reacted swiftly, accusing Moscow of deliberately probing NATO’s response. Ukrainian Deputy Foreign Minister Andriy Sybiha warned that Russian President Vladimir Putin would continue to “test the West” until confronted with decisive action. “Putin is escalating, expanding his war and testing the West. A weak reaction today will only provoke Russia further, and Russian missiles and drones will fly deeper into Europe,” Sybiha posted.

The overnight events underscored the fragility of NATO’s eastern flank. For more than three years, Russian drones and missiles have occasionally strayed into alliance territory, but until now none had been brought down by member states.

Yet the latest violation raises questions about how long the alliance can tolerate repeated drone incursions without a stronger response. Some analysts argue that Moscow is deliberately pushing the boundaries, gauging the willingness of NATO capitals to defend their skies while stopping short of triggering a full confrontation.

Republican Congressman Joe Wilson condemned the drone strikes on Poland as “an act of war”, accusing Moscow of directly testing NATO’s resolve. He urged President Donald Trump to impose sweeping sanctions aimed at bankrupting Russia’s war machine and to provide Ukraine with long-range weapons capable of striking Russian territory. “Putin is no longer content just losing in Ukraine while bombing mothers and babies, he is now directly testing our resolve in NATO territory. Putin stated that “Russia knows no borders.” Free and prosperous nations will teach Russia about borders”, wrote he on X.

For Poland, the incident has already become a test of political and military resolve. Warsaw must balance domestic security concerns with its role as a frontline NATO state and the main logistical hub for Western support to Ukraine. The government’s rapid decision to close airports and authorise live fire demonstrated readiness to act, but it also exposed the vulnerability of civilian infrastructure to Russia’s war spilling across borders.

In the meantime, Polish investigators are working to locate the wreckage of the drones and verify whether they were intended to hit Ukrainian targets but strayed off course, or whether the crossing was deliberate. Either way, the precedent has been set: Russian drones have now been destroyed over Polish territory, and the security consequences reverberate far beyond Warsaw.

In recent months, other NATO members along Russia’s periphery have also reported drone incidents, underlining a broader pattern. Romania has repeatedly found fragments of Russian drones on its territory near the Danube delta, prompting protests to Moscow and appeals for stronger air defence. Lithuania has logged incursions of unidentified UAVs crossing from Belarus, which Vilnius views as part of hybrid tactics coordinated with the Kremlin. Estonia too has recorded airspace violations, with Tallinn warning that drone flights near its border villages are designed to intimidate local populations and test NATO radar coverage. None of these countries, however, had until now ordered drones to be physically shot down, making the Polish precedent a significant escalation in the alliance’s eastern security posture.
