On the night of October 4, 2025, units of the Ukrainian Defense Forces struck important military and infrastructure facilities of the aggressor on the territory of Russia and in temporarily occupied Ukrainian territories. This information was disseminated by the General Staff.
According to the report from the General Staff of the Ukrainian Armed Forces, the enterprise 'Kirishinefteorgsintez' in the city of Kirishi, Leningrad Oblast, Russian Federation was struck. This company is one of the largest oil refineries in Russia, with an annual capacity of 19.8 million tons. The consequences of the attack are currently being assessed.
Damage to Facilities and Military Equipment
The 'Kirishinefteorgsintez' plant is a key player in the oil chemistry sector in Russia. This factory belongs to the holding 'Surgutneftegaz' and has significant capacity in oil refining. Various oil products are produced here, including gasoline, diesel fuel, aviation fuel, and more.
In addition, information has also emerged about damage to the small missile ship 'Buyan-M' near Lake Onega (Republic of Karelia, Russia), a radar complex 'Garmon' and a transporting-loading vehicle of the missile system 'Iskander' in the Kursk region.
The General Staff noted that in addition to strikes deep within Russia, a strike was also delivered on the command post of the 8th Army of the Armed Forces of the Russian Federation on temporarily occupied territory of Donetsk. These actions are aimed at undermining the military-economic potential of the Russian Federation, particularly in the areas of logistics and combat equipment supply.
The events that occurred on the night of October 4, 2025, indicate an increase in tension between Ukraine and Russia. The strikes of the Ukrainian Defense Forces on the aggressor's facilities on the territory of Russia and in the occupied territories have strategic significance for weakening Russia's military capabilities and influencing the situation in the region. These events may have serious consequences for both countries and lead to further escalation of the conflict.
