Polish and allied aviation operations in Polish airspace concluded by 4:46 PM UTC on September 13th, 2025, with ground air defense and radar systems returning to standard operations, according to the Polish Army Operations Command. The operation was conducted in response to Russian unmanned air objects near the Polish border and over Romanian territory, following earlier air threat warnings issued by both nations. The Polish Army Operations Command stated they continue to monitor the situation in Ukraine and remain ready to ensure Polish airspace security. During the reporting window, which began at 4:32 PM UTC, the Polish Army Operations Command confirmed the completion of preventive monitoring and joint air operations. This follows earlier actions within the past hour, where Polish helicopters and fighters were deployed, and a RO-Alert message was issued in northern Romania's Tulcea County warning of potential drone activity. The Romanian alert concerned the risk of falling objects in the airspace. Reports from earlier in the day indicated that Polish and NATO fighter jets were scrambled around 3:03 PM UTC in response to potential drone activity over western Ukraine. Poland's ground air defense systems had reached their highest state of combat readiness. Lublin Airport in eastern Poland remained closed due to "unplanned military activity related to ensuring state security." Separately, there were unconfirmed reports of unusual movement on the Belarus border with Poland. Previous warnings issued between 4:02 PM UTC and 4:16 PM UTC saw air raid alerts in six poviats of Poland's Lubelskie Voivodeship due to a threat of aerial attack. Simultaneously, a Russian Shahed-type drone reportedly entered Romanian territory. Polish citizens were advised to be careful and follow emergency service instructions during these alerts, with sirens activated in Świdnik.
