Polish President Karol Nawrocki said on Wednesday after the Russian drone attack that during an emergency meeting of the country's National Security Bureau, the possibility of applying Article 4 of the North Atlantic Treaty was discussed (Article 4 provides for mutual consultations between NATO member states when, in the opinion of any of them, there is a threat to the territorial integrity, political independence or security of any of the parties, which prompts the start of official consultations - IF-U).
