The Ukrainian Air Force reported on Friday, September 13th, 2025, that managed aviation bombs were being deployed by hostile tactical aviation targeting the Sumy region. The specific timing of this reported deployment falls within the current reporting window, which began at 6:47 PM UTC and concluded at 7:16 PM UTC. This development follows earlier reports of widespread air raid alerts across Ukraine, including in the Dnieper region, with threats of drone and ballistic missile attacks originating from Crimea. Previously, a Russian drone had entered Romanian airspace for approximately 50 minutes before crashing southwest of Chilia Veche, prompting Romania to scramble F-16 jets. The Romanian Ministry of Defense confirmed that Russian drones entering Romanian airspace would be shot down. Earlier on Friday, between 4:02 PM UTC and 4:46 PM UTC, Poland had issued air raid warnings in six poviats of its Lubelskie Voivodeship due to aerial attack threats, concluding allied aviation operations by 4:46 PM UTC. Polish and allied aviation operations had concluded earlier in the day after air raid warnings were issued in Poland's Lubelskie Voivodeship due to aerial attack threats. Poland's Lublin Airport had remained closed due to "unplanned military activity related to ensuring state security." In a separate incident, an unverified social media post claimed extensive drone activity, listing over 1500 "birds" including various types and mentioning a large aircraft in the air for 24 hours. The WSJ reported that since President Donald Trump took office, Russia has significantly increased its aerial attacks against Ukraine, launching 6,300 drones in July 2025 alone.
