Polish fighter jets were heard over Lublin, Eastern Poland, between 12:00 AM and 12:15 AM UTC on September 10th, 2025, amid ongoing reports of Russian drone incursions and activity. Warsaw Airport has been closed, according to multiple unconfirmed reports, as air defense systems remain on high alert. This activity follows earlier incursions on September 9th involving multiple Shahed drones originating from the Volyn region. Reports from Ukrainian military channels indicate that 10 UAVs were tracked moving from Volyn towards the Lviv region during the early hours of September 10th. Additionally, Ukrainian Air Force channels issued warnings about threats to Kyiv and Zhytomyr from UAVs, and noted enemy tactical aviation activity in eastern and northeastern directions with aircraft potentially conducting strikes in frontal areas. The Polish Operational Command stated that ground-based air defense and radar reconnaissance systems are at peak readiness. This period of heightened activity coincides with previous reports from September 9th detailing Polish F-16 and Dutch F-35 deployments in response to drone incursions. Rzeszów Airport was temporarily closed due to "unplanned military activity related to ensuring state security." The Polish border with Belarus remains closed due to ongoing Russian-led military exercises, "Zapad-2025."
