Kyiv warned Poland about the Russian drone threat before the attack occurred. On the night of 10 September, nearly two dozen Russian drones may have entered Polish airspace, although this figure is not final, Ukrainian President Volodymyr Zelenskyy said.

This incident marked the first time since Russian drones massively violated the territory of a NATO member state and prompted the country to down them with strategic aviation. 

“Ukrainian forces informed the Polish side through the appropriate channels about the movement of Russian drones. Around 00:50 Kyiv time, the first crossing of the Ukrainian-Polish border by a Russian drone was recorded,” the Ukrainian president noted.

At least two drones that entered Poland used Belarusian airspace. Meanwhile, dozens of other drones moved along the Ukraine-Belarus border and in western regions of Ukraine, approaching Ukrainian and potentially Polish targets.

Ukrainian air defenses in action

Zelenskyy emphasized that Ukrainian defenders destroyed more than 380 Russian drones of various types, including at least 250 Shaheds.

“The number of Russian drones that crossed into Polish territory and penetrated deeply may be higher than previously reported. We are checking,” the Ukrainian president said. 

Ukrainian forces continue to analyze debris to clarify drone types. The president stressed that only joint and coordinated action with allies can ensure reliable airspace protection.

NATO and regional security

Meanwhile, the Russian Ministry of Defense denied involvement in the attack.

The incident prompted Poland to appeal to NATO, which activated Article 4 of the North Atlantic Treaty. This allows consultations regarding threats to territorial integrity and security, but does not automatically trigger a military response as Article 5 does. Polish F-16s and F-35s were scrambled to intercept drones, though most threats were neutralized by Ukrainian air defenses.

The attack happened in the midst of discussions by European and American allies on security guarantees for Ukraine. 

Intelligence insights

Joint Russian-Belarusian military exercises, “Zapad-2025,” are currently underway in Belarus, with the active phase planned for 12–16 September. During these exercises, scenarios include simulated attacks on Poland and nuclear weapons deployment, UkrInform reports. 

Kyrylo Budanov, the head of Ukraine’s Main Intelligence Directorate, stated that the active phase will involve serious information pressure, accompanied by staged leaks and information provocations.
