NATO ambassadors held urgent consultations Wednesday after multiple Russian drones entered Polish, and therefore NATO, airspace and some were shot down by Polish and Dutch fighter jets, alliance and Polish officials said.
Polish Prime Minister Donald Tusk told Parliament that the meeting at NATO headquarters took place under Article 4 of the treaty that created the alliance. Article 4 states, “The Parties will consult together whenever, in the opinion of any of them, the territorial integrity, political independence or security of any of the Parties is threatened.”
The consultations were held as part of a regular meeting of ambassadors from NATO’s 32 member states, known as the North Atlantic Council, officials said. The incident in Poland occurred three days after what has been described as Russia’s largest aerial attack on Ukraine since the war began, underscoring heightened tensions on NATO’s eastern flank.
Article 4 is the shortest of the treaty’s 14 articles and is designed to prompt discussion and coordination among allies when one of them perceives a threat. Bob Deen, an analyst at the Clingendael think tank in The Hague, said the provision "is designed to promote better coordination and understanding within the alliance on external threats. It gives all allies the opportunity to urgently put certain threats or developments on the agenda of the North Atlantic Council." Deen’s comments were provided by email to The Associated Press.
Consultations under Article 4 do not automatically trigger NATO’s mutual-defense clause, Article 5, which states that an attack on one ally is considered an attack on all and obliges a collective response. Article 5 has been invoked only once in NATO’s history, in response to the Sept. 11, 2001, terrorist attacks on the United States.
Article 4 has been used increasingly in recent years, often as a mechanism to bring allied attention to regional security concerns without committing the alliance to a military response. Turkey invoked Article 4 multiple times between 2003 and 2020 in relation to cross-border tensions with Syria and Iraq. In 2014 Poland first requested Article 4 consultations following Russia’s annexation of Crimea, and in February 2022 Poland joined seven other eastern and central European NATO members in requesting consultations after Russia launched a full-scale invasion of Ukraine.
Poland’s decision to call for Article 4 talks signals Warsaw’s intent to elevate the incident within NATO’s political and security agenda and to seek coordinated measures, including increased situational awareness and defensive readiness, from alliance partners. Officials did not say the consultations had led to any specific new measures, emphasizing instead that the procedure is aimed at joint assessment and information-sharing.
NATO spokespeople and allied diplomats said the alliance continues to monitor developments closely and to provide support to member states facing airspace incursions. The use of Article 4 allows allies to discuss potential risks and responses collectively while preserving the distinction between consultative steps and the collective-defense commitments under Article 5.
