Poland scrambles defences as Russian drones breach airspace

September 11, 2025

The Russia-Ukraine war entered a new and dangerous phase this week when Poland confirmed that Russian drones had repeatedly violated its airspace during a large-scale assault on Ukraine. Warsaw scrambled its own and Nato aircraft to intercept and shoot down some of the drones, marking the first direct engagement between a Nato member and Russian assets since the war began in 2022.

Unprecedented violations

Poland’s armed forces announced that its airspace had been “repeatedly violated” during the Russian attack on Ukraine. The military’s operational command said on social media that the incursion represented “an unprecedented violation” and described it as an act of aggression that posed a serious threat to citizens’ safety.

Operations were launched to identify and neutralise targets, while searches were carried out for drones that had been downed. Local police in Czosnówka, in eastern Poland, reported finding a damaged drone. Ukrainian media suggested at least one drone had headed toward Rzeszow, a western Polish city that serves as a logistics hub for military supplies to Ukraine.

Prime Minister Donald Tusk confirmed that a military response was underway and said he was in constant contact with President Karol Nawrocki and the armed forces. Defence Minister Wladyslaw Kosiniak-Kamysz added that the Territorial Defence Forces had been activated for ground searches, while Poland remained in close coordination with Nato command. He urged citizens to remain calm and to report any discovery of drone fragments.

 Closures and restrictions

The immediate impact of the drone incursions was felt in Poland’s air traffic. Warsaw International Airport, the country’s largest, was closed as a precaution before being reopened later the same day. The US Federal Aviation Administration reported that three other airports had also been temporarily shut due to “unplanned military activity related to ensuring state security.” The Polish military issued advisories urging people to remain indoors, particularly in the eastern provinces of Podlaskie and Lublin, which border Belarus and Ukraine, and in Masovia, which includes the capital Warsaw. The timing of the incident was notable. It came a day after newly elected President Nawrocki warned that Russian President Vladimir Putin could move beyond Ukraine and threaten other countries. “We do not trust Vladimir Putin’s good intentions,” Nawrocki said during a press conference in Helsinki.

 International response

The violations occurred amid Russia’s largest aerial assault on Ukraine since the invasion began. In recent days, Russian strikes have hit residential areas around Kyiv, including an attack that killed 24 civilians in the village of Yarova in Donetsk. Over the weekend, more than 800 drones were deployed in what Ukraine described as Moscow’s biggest attack to date.

The breach of Polish airspace prompted strong international condemnation. Ukrainian Foreign Minister Andriy Sybiga said the incident showed Russia was escalating the war and testing Western resolve. “The longer he faces no strength in response, the more aggressive he gets,” Sybiga warned. Lithuania’s foreign minister Kestutis Budrys urged Nato to respond with capabilities rather than statements, warning that no country in Europe was safe while Putin pursued the war. Swedish Prime Minister Ulf Kristersson said the violations were unacceptable and reaffirmed support for Poland as both a Nato ally and EU member.

Norway’s foreign minister Espen Barth Eide echoed those concerns, calling the incident “deeply concerning and entirely unacceptable.” In the United States, Secretary of State Marco Rubio confirmed he had been briefed on the situation, while other lawmakers said the repeated incursions should not be ignored. Implications for Nato Analysts say the developments carry major implications for Nato.

While Russian drones and missiles have occasionally strayed into Nato territory in the past, none had been intercepted or shot down by alliance members until now. The fact that Poland engaged the drones raises the stakes significantly. Former US defence official Jim Townsend told the BBC that multiple drones entering Polish airspace was unlikely to be accidental.

“This is more than likely a test — a test that Nato has to answer,” he said. Ben Hodges, a former commander of US Army forces in Europe, told Reuters that the scale of incursions showed they were deliberate attempts to probe Nato defences and early warning systems. US Senator Dick Durban said Putin was testing Nato’s resolve to protect Poland and the Baltic states. “After the carnage Putin continues to visit on Ukraine, these incursions cannot be ignored,” he said.

A turning point?

The drone incident has underscored the fragility of Europe’s security environment. It highlights how the war in Ukraine, now in its fourth year, can spill across borders and risk a direct confrontation between Russia and Nato. For Poland, the breach is not only a violation of sovereignty but also a reminder of its frontline role in Europe’s defence
