The General Staff of the Armed Forces of Ukraine confirmed a series of successful strikes against Russian strategic infrastructure in the early hours of Sunday, April 5, including a massive hit on one of Russia’s largest oil refineries.
The “Lukoil-Nizhegorodnefteorgsintez” refinery in Kstovo, Nizhny Novgorod region, was struck, sparking a large-scale fire at the facility. The plant is a critical asset for the Russian military-industrial complex, providing nearly 30% of the gasoline consumption for the Moscow region and directly supplying fuel to the occupying forces in Ukraine.

With an annual capacity of 17 million tons, the refinery produces over 50 types of products, including aviation and diesel fuel.
Simultaneously, Ukrainian forces targeted the Port of Primorsk on the Baltic Sea, another vital hub for Russia’s oil exports. While Leningrad regional governor Alexander Drozdenko initially denied damage to the pipeline, he later confirmed a fuel leak caused by a shrapnel hit on a storage tank. Ukrainian drone forces commander Robert Brovdi confirmed the strike, noting that the “unmanned systems forces once again paid a gracious visit” to the Transneft-owned facility.
In occupied Crimea, Ukrainian units struck an aviation equipment storage warehouse in Saky. These operations were bolstered by strikes on Russian troop concentrations in the Dnipropetrovsk, Zaporizhzhia, and Donetsk regions, specifically near the settlements of Berezove, Novomykolaivka, Huliaipole, and Yalynske.
