Poland invokes NATO Article 4 after Russian drones breach its airspace

Poland requested NATO Article 4 consultations on September 10, 2025, after Polish air defenses shot down Russian drones that had crossed into Polish territory while targeting Ukraine. It was Poland's second Article 4 invocation since Russia's 2022 full-scale invasion. NATO Secretary General Mark Rutte convened emergency consultations and affirmed the alliance's commitment to territorial integrity, though no Article 5 collective defense clause was triggered.
