On the night of 9-10 September at least 21 Russian drones entered Polish airspace, the largest incursion into NATO territory of the war. Polish, Dutch, Italian and American aircraft operated in the airspace and air defence systems were placed on high alert; up to four drones were shot down. Warsaw, Warsaw Modlin, Rzeszów and Lublin airports closed for the night. One drone crashed at Oleśno near Elbląg, more than 200 km from the eastern border. Poland invoked Article 4 of the North Atlantic Treaty in response.
