A plant in Russia's Bryansk region, identified as JSC Karachevsky Zavod “Elektrodetal,” was struck during the reporting window. The enterprise develops and produces electrical connectors for military and industrial use. The source, NEXTA TV, reported this development on September 29th, 2025. This strike follows President Donald Trump's authorization for Ukraine to conduct long-range drone and missile strikes inside Russia, confirmed by White House Special Envoy Keith Kellogg. Some of these strikes require prior Pentagon approval. The Karachevsky Electronics Plant in Bryansk was also reportedly ablaze overnight September 28th to 29th, according to previous reports. Previous reports indicated temporary flight restrictions at airports in Kaluga and Tambov between 10:37 PM and 11:06 PM UTC on September 28th, coinciding with the earlier fire at the Karachevsky Plant. The plant is known for producing key electrical components for the Russian defense industry. Residents in Eastern Poland reported hearing fighter jets near the border with Ukraine between 2:06 AM and 3:06 AM UTC on September 29th, amidst heightened regional tensions. This activity occurred in the context of ongoing military operations and previous Russian missile and drone attacks against Ukraine.
