Poland scrambled aircraft and placed air-defense and radar systems on combat readiness for a second time in one day on September 17 due to Russian attacks on Ukraine, temporarily suspending flights at Lublin and Rzeszów airports. Poland's Deputy Defence Minister said an order authorizing air defense measures remains in effect amid continued concern over Russian drone incursions and hybrid threats near NATO's eastern flank. On the morning of September 18, Rzeszów and Lublin airports suspended operations for a third consecutive day, reflecting the persistence of the security threat and its escalating disruption to regional air travel.
