Over the past hour, between 4:01 AM and 5:01 AM UTC on September 15th, 2025, the Ukrainian Air Force reported continued drone activity in the northern parts of the Chernihiv and Sumy regions, with one UAV heading west in Chernihiv and others changing course in Sumy. Additionally, an enemy reconnaissance UAV was detected south of Zaporizhzhia, with potential for air defense engagement, according to the Air Force of the Armed Forces of Ukraine. These reports follow an earlier period where drone activity was noted in the Sumy and Chernihiv border regions, as well as in Zaporizhzhia. The specific details provided in the past hour indicate a continuation of these observed movements. Separately, a message posted on September 9th, 2025, from a user identified as "МАДЯР🇺🇦" on the "Starlink" platform stated "Starlink lay down all the front," though the precise meaning and context of this message remain unclear. Previous reports from yesterday indicated that Polish President Karol Nawrocki approved the stationing of NATO troops on Polish territory as part of Operation "Eastern Guardian," and that an ammunition detonation on a train in the Kyiv region disrupted rail traffic.
