Ukrainian Air Force monitoring channels reported on Saturday, September 14th, 2025, at 00:05 EEST (23:05 UTC, September 13th) that an enemy unmanned aerial vehicle (UAV) was detected in the Sumy region and was proceeding towards the Poltava region. This development occurred within the current reporting window. Earlier in the reporting window, Ukraine's Air Force had stated on Friday, September 13th, 2025, that managed aviation bombs were deployed by enemy tactical aviation targeting the Zaporizhzhia and Donetsk regions. Reports from the Kyiv region also indicated sounds of explosions, though the "єРадар" channel noted there was no associated air anxiety. The "Реальний Київ" channel confirmed repeated explosions in the Kyiv region during this period. In parallel, the "ЗАГРОЗА З НЕБА" channel announced "Starts to Donetsk!" and a "Threat from the sky." Separately, a Polish army presence was reported on the border, with a source linking to a social media post from "ortadogu2110." The new source information regarding UAV movement in the Sumy region and its course towards Poltava was based on Russian sources, outlining approximate flight routes of Ukrainian strike UAVs. Previous reports indicated that multiple Russian Aerospace Forces aircraft landed at Lida Air Base in Belarus on Friday, September 13th, 2025, around 09:00 UTC, linked to the "West 2025" military exercise. This deployment occurred amidst heightened regional aerial operations and increased training flights by the Belarusian Air Force. On the night of September 9th to 10th, a Belarusian Air Force Su-30SM reportedly shot down a UAV during large-scale Russian UAV attacks on Ukraine and Poland. Additionally, earlier in the reporting window, managed aviation bombs were reported targeting the Sumy region, following wider regional air raid alerts and threats of drone and ballistic missile attacks originating from Crimea. Poland had issued air raid warnings in its Lubelskie Voivodeship on Friday due to aerial attack threats, and its Lublin Airport was closed due to "unplanned military activity related to ensuring state security."
