Tensions in Ukraine spilled over into Poland as several Russian drones violated its airspace in what officials described as an “act of aggression”. In response, Poland invoked Nato ’s Article 4 with Prime Minister Donald Tusk confirming that Polish forces, with Nato support, shot down several drones overnight, marking the first time a member of the alliance has used weapons against Russian objects in its territory.
The incident came during Russia’s largest aerial assault on Ukraine since the war began, with hundreds of drones and missiles targeting cities, including Kyiv and Lviv. Several drones strayed into Poland, prompting Warsaw to close airspace and scramble aircraft alongside NATO allies, including the Netherlands and Germany.
Prime Minister Tusk told parliament that Poland is now nearer to open conflict than at any time since World War Two. "I have no reason to claim we're on the brink of war, but a line has been crossed... This situation brings us the closest... since World War Two."
The Kremlin dismissed the accusations and called out EU, Nato's "usual practice" of blaming Russia "without backing it up"
“We wouldn’t like to comment on this,” said spokesman Dmitry Peskov, adding it was a matter for the Russian defence ministry. Asked about accusations, he said: “The leadership of the EU and Nato accuse Russia of provocations... usually without backing this up.”
What happened - Explained in 10 points
Nato's Article 4 formally invoked. What is it?
For the first time since Russia’s full-scale invasion of Ukraine in 2022, Poland has triggered Nato's Article 4, demanding allied consultations on its security. Article 4 allows any member to bring concerns about threats to its territorial integrity, political independence or security before the North Atlantic Council.

Article 4 of Nato's founding treaty allows any member state to request consultations when it perceives a threat to its territorial integrity or security.
Since 1949, Article 4 has only been invoked a handful of times, including by Poland in 2014 after Russia’s annexation of Crimea, and by Turkey on multiple occasions in response to threats from Syria. This latest invocation underscores the seriousness with which Warsaw views the drone incursions. While Article 4 does not obligate allies to take military action, it often results in joint measures or deployments.
Where were the drones shot down?
Polish Defence Minister Wladyslaw Kosiniak-Kamysz confirmed that more than 10 objects had crossed into Polish airspace during Russia’s overnight barrage against Ukraine. He said several drones that posed direct threats were intercepted and destroyed with the assistance of NATO forces.
Poland's interior ministry reported that the overnight airspace violation damaged a house and a car. "We have found seven drones and projectile debris... of unknown origin," said spokeswoman Karolina Galecka. So far, seven drones and unidentified projectile fragments have been found, alongside damage to property, according to authorities.
The Royal Netherlands Air Force deployed F-35 fighter jets, while German Patriot batteries were placed on alert. Italy also contributed early warning aircraft and refuelling support. Local officials reported damage in villages such as Wyryki in the Lublin region, where one house was struck, though no casualties occurred.
Chopin Airport in Warsaw suspended flights for several hours due to military activity. The Polish armed forces urged residents not to approach debris from downed drones, warning of hazardous materials. While Poland has faced occasional airspace intrusions in the past, officials described this incident as “unprecedented” in scale and danger, underlining the risks posed by Russia’s escalating air campaign.
Russia escalates air campaign in Ukraine
Ukraine’s air force reported that Russia launched 415 drones and over 40 missiles overnight, striking cities in the centre and west of the country. In Lviv, close to the Polish border, residential areas and infrastructure were damaged, while in Khmelnytskyi, a sewing factory and petrol station were destroyed, injuring three. Vinnytsia, Zhytomyr and Cherkasy regions also reported deaths and significant damage to homes and industry.
President Volodymyr Zelenskyy said Russia was deliberately pushing the war closer to Nato territory and warned that partners must respond decisively. Ukrainian officials described the scale of the assault as one of the largest since February 2022, with civilian casualties mounting. Russia’s defence ministry claimed it had intercepted 122 Ukrainian drones over Crimea and Russian regions, portraying its actions as defensive.
EU reacts with alarm
EU foreign policy chief Kaja Kallas said the drone violations in Poland marked the “most serious European airspace violation since the war began”. She stressed that evidence suggested the incursion was intentional. Lithuania’s President Gitanas Nauseda accused Moscow of “deliberately expanding its aggression” against Europe, while Estonia’s foreign minister Margus Tsahkna said Russia posed a “threat not only to Ukraine but to all of Nato”.
Sweden’s Prime Minister Ulf Kristersson echoed those concerns, calling the breach “unacceptable”. The reaction reflected growing unease among Europe’s eastern states, who have long warned that Russia could test the alliance’s defences. Officials in Brussels said the latest events had further strengthened the case for reinforcing NATO’s eastern flank.
'Nato committed to defending every km of allied territory'
NATO officials confirmed that allied forces actively supported Poland in intercepting hostile objects overnight. Colonel Martin O’Donnell of Supreme Allied Powers Europe said it was the first time NATO aircraft had engaged potential threats inside a member’s airspace during the war.
Dutch F-35s scrambled to assist Polish jets, while German, Italian and multinational NATO aircraft were deployed for support and monitoring. The alliance stressed that its defences had worked as intended and demonstrated unity in protecting Polish sovereignty. NATO spokesperson Allison Hart confirmed that ambassadors would discuss the incident at a pre-planned meeting, now expanded to address the emergency. “NATO remains committed to defending every kilometre of allied territory,” she said.
How the Polish reacted
The drone strikes caused disruption across parts of eastern Poland. In Wyryki, villagers reported an explosion that damaged a home, though occupants escaped unhurt. Authorities closed airspace over Warsaw and surrounding areas, grounding flights at Chopin Airport before reopening several hours later. Defence forces urged civilians to report debris and activated territorial units to assist in searches. Officials stressed the dangers of touching fragments, warning they could contain explosives or toxic materials. P
Prime Minister Tusk called an extraordinary cabinet meeting to assess security, while President Nawrocki said protecting citizens remained the top priority. The incidents underscored how Poland, already hosting more than a million Ukrainian refugees, is directly exposed to the consequences of the war.
Not the first airspace violation
This is not the first time Russia-linked objects have entered Poland, but officials said the scale set it apart. In August 2023, a Russian drone exploded in a Polish cornfield, an incident Warsaw labelled a “provocation”. Earlier in March, a Russian missile briefly crossed Poland en route to Ukraine, forcing jets to scramble.
In November 2022, a Ukrainian anti-aircraft missile tragically killed two civilians after straying across the border. These episodes have fuelled debates about Nato’s rules of engagement and the threshold for invoking Article 5. Until now, Poland had not engaged intruding objects directly. Wednesday’s shoot-down therefore represents a significant change in posture, with Warsaw signalling it will act forcefully against incursions.
Ukraine warns of wider danger
Ukrainian officials said Russia’s drone incursions into Poland showed President Vladimir Putin was “testing the West”. Foreign Minister Andriy Sybiga argued that Moscow was emboldened by weak responses to past provocations.
“The longer he faces no strength in response, the more aggressive he gets,” Sybiga warned. Zelensky echoed the sentiment, calling the overnight events a dangerous precedent. Kyiv has urged Nato to adopt stronger deterrence measures, arguing that Russia is deliberately probing weaknesses. Ukraine’s military reported that at least eight drones launched at its territory diverted toward Poland. Officials said this demonstrated Moscow’s willingness to broaden the scope of attacks, even at the risk of triggering Nato confrontation.
Domestic political backdrop in Poland
The escalation comes at a sensitive moment in Polish politics. Newly elected President Karol Nawrocki has taken a hard line on Russia, warning only days earlier that Putin could invade other countries beyond Ukraine.
Prime Minister Tusk, addressing parliament, emphasised that Warsaw was prepared to defend its territory and called the drone strikes a “large-scale provocation”. The extraordinary cabinet meeting underscored the gravity with which the government views the situation. Poland, a staunch supporter of Ukraine since the invasion, has provided aid, hosted refugees and served as a vital logistics hub for Western assistance.
Putin emboldened amid global manoeuvres
The timing of the drone incursions raised questions about Russia’s broader strategy. The escalation followed Vladimir Putin’s visit to China, where he met Xi Jinping and North Korea’s Kim Jong Un in a display of authoritarian unity.
In Poland, officials linked the drone incidents to joint Russian-Belarusian military exercises, Zapad 25, set to begin near their border. Tusk announced that Poland would close its frontier with Belarus as a precaution. European leaders interpreted the timing as deliberate, a show of strength aimed at unnerving Nato.
