Russian Drones Over Poland
A Russian violation of Polish airspace on the night of 9-10 September 2025 has caused Poland to invoke Article 4 of NATO, requiring a consultation between member states to decide whether the sovereignty or political independence of any member state has been violated. This is not the first violation of NATO airspace since the beginning of the Russia-Ukraine conflict in 2022 and was followed by a violation of Romanian airspace two days later.
