Poland has heightened its air defence posture, following repeated alleged incursions into its airspace in recent weeks.
The Polish Air Force launched preventive air patrols on September 17 aimed at securing the eastern part of Polish airspace.
Warsaw officially blamed Russia, but Moscow has denied allegations that it is targeting NATO nations.
Russia’s Ministry of Defence said on September 19 Moscow’s forces had seized 5,300 square kilometres (2,050 square miles) and more than 220 settlements in Ukraine since the start of 2026.
