Poland closed all railway border crossings with Belarus on September 14th, 2025, following a series of Ukrainian drone attacks targeting critical Russian infrastructure, including oil refineries and railway lines. This action was reported by NOELreports and coincides with Ukrainian intelligence confirming strikes in the Chernihiv region, specifically in Losynivka, north and on the outskirts of Nizhyn, Dobryanka, and towards Baturin. Explosions were also reported in Severodonetsk, Luhansk region, after a UAV arrival, according to Exilenova+. In the Kupyansk direction, intelligence from the 77th Separate Airmobile Dnieper Brigade of the State Security Service of Ukraine reported that a T-72 tank crew destroyed an enemy group of four individuals attempting to establish a position near an apartment building. The engagement occurred from a distance of 9,100 meters, with the crew reportedly making five accurate shots. Earlier on September 14th, Russian air defenses intercepted or jammed 52 drones and destroyed one Iskander-M missile and six additional drones overnight. Pulkovo Airport in St. Petersburg temporarily suspended flights for approximately one hour due to these events. Separately, footage confirmed Ukrainian forces advancing west of Volodymyrivka on the Dobropillia axis, with a Russian unit encircled near Kucheriv Yar. Ukraine has conducted 17 strikes on 12 Russian oil refineries over 45 days, targeting facilities representing 42% of Russia's total oil refining capacity, according to an assessment by @igorsushko. The latest refinery strike mentioned occurred on September 14th at the Kirishi Oil Refinery. These ongoing attacks are part of a broader pattern of Ukrainian operations, which also included an increase in drone and missile activity in August that struck oil facilities, refineries, airfields, and railway sites. Ukraine's HUR (Main Intelligence Directorate) is credited with striking key Russian railway routes, as reported by Babel.ua. On September 13th, a mine explosion near Maloarkhangelsk killed two Rosgvardiya troops and halted the Orël–Kursk line, causing delays to over 15 trains. That night, another strike derailed a train and destroyed fuel tankers on the Strogonovo–Mshinskaya line, both identified as critical for Russian logistics in the Kharkiv and Sumy directions. These incidents are consistent with previous reports of rail disruptions in Russia's Leningrad Oblast, including a locomotive with 15 tankers derailing, impacting traffic and commuter trains, and an electric locomotive derailment in Gatchina district that killed the operator. In the Luzhsky district of Leningrad Oblast, three freight cars derailed on the Stroganovo–Mshinskaya line. At 14:00, there were 405 vehicles in the queue for manual inspection by Tamani at the Crimean Bridge, with an estimated waiting time of two hours. Additionally, 710 vehicles were in the queue for manual inspection by Kerch, with an estimated waiting time of three hours. In a separate development, Donald Tusk commented on growing pro-Russian sentiments in Poland, stating that politicians must address this rather than capitalize on it, calling it a test for the patriotism and maturity of the Polish political class.
