Polish military aircraft were heard over Warsaw at approximately 02:00 UTC on September 10th, 2025, as the country continues to monitor Russian drone activity. A journalist for Poland's Polsat News reported hearing military planes over their home in Warsaw around this time, adding to ongoing security concerns. Earlier in the reporting window, between 00:00 UTC and 00:15 UTC on September 10th, Polish fighter jets were reported over Lublin, Eastern Poland. Warsaw's Modlin Airport and Warsaw's Chopin Airport were closed due to "unplanned military activity related to ensuring state security." The Polish Operational Command stated that ground-based air defense and radar reconnaissance systems are at peak readiness. This activity follows reports from Ukrainian Air Force channels indicating approximately 55 UAVs were in the air, with a significant number heading towards or through the Kyiv region and several more directed towards Poland. Ukrainian Air Force channels also issued warnings of UAV threats to Lutsk, Lviv, and Kyiv, and reported drone activity in the north of Ternopil region heading southwest. As of 03:40 UTC, all strategic aviation boards were reported to be planted at base aerodromes. Representative Joe Wilson previously stated that Russia is attacking NATO ally Poland with Iranian Shahed drones, calling it an "act of war." This escalation follows previous reports of Polish F-16 and Dutch F-35 deployments in response to drone incursions, with Rzeszów Airport having been temporarily closed due to similar security concerns. The Polish border with Belarus remains closed due to ongoing Russian-led military exercises, "Zapad-2025."
