Yes. On September 17, 2026, Poland scrambled military aircraft, issued air-raid warnings in eastern regions, and temporarily closed airports in Rzeszów and Lublin after Russian strikes on western Ukraine came close to the Polish border, Reuters reported.
The Polish army said no violation of Polish airspace was recorded and that military aircraft later finished their operations. Prime Minister Donald Tusk also told parliament that intelligence agencies warned Russia may plan “hybrid” drone and missile attacks against countries supporting Ukraine.
