10月4日，烏克蘭武裝部隊總參謀部發布通報稱，當天烏軍對位於俄羅斯列寧格勒州基里希市的 基里希石油化工廠實施打擊。通報指出，現場出現爆炸與火災，但具體命中效果仍在核實中。基里希石油化工廠是俄羅斯境內規模最大的煉油企業之一，年煉油能力達1840萬噸原油，因此這次攻擊對俄能源基礎設施的打擊意義重大。

此外，烏軍還在多個戰線對俄軍目標發起攻擊。在俄屬卡累利阿共和國奧涅加湖區域，一艘小型導彈艇“布揚-M”遭到擊中，其損毀程度仍在確認中。在庫爾斯克州，烏軍摧毀一座俄軍“手風琴”雷達站，以及一輛屬於俄軍“伊斯坎德爾”戰術導彈系統的運輸裝填車。同時，烏軍對駐扎在 頓涅茨克地區的俄軍第8集團軍指揮所進行打擊，目標已命中，但具體損失仍待核實。目前，俄羅斯方面對這些攻擊尚未作出回應。

與此同時，烏克蘭國內也發生與俄軍襲擊相關的事件。據參考消息報導，烏克蘭蘇梅州軍事行政長官奧列格·格里戈羅夫於4日通過社交媒體發文稱，一列從紹斯特卡市開往基輔市的客運列車遭到俄軍襲擊。根據烏克蘭媒體報導，襲擊造成約 30 人受傷。格里戈羅夫表示，襲擊導致部分乘客受傷，醫護人員及烏克蘭國家緊急情況局工作人員已在現場進行救治，但他未透露受傷人數及襲擊具體細節。

烏克蘭國家公共廣播公司援引紹斯特卡地區軍事管理局代理局長奧克薩娜·塔拉修克的說法稱，俄軍發動襲擊時，客運列車正停靠在紹斯特卡市火車站，襲擊引發列車起火，約30名乘客受傷，受傷人員已被送往醫院救治，目前受傷人數仍在進一步核實中。

整體來看，10月4日的事件顯示，烏克蘭軍方持續針對俄軍能源基礎設施、導彈系統及指揮中心發動精準打擊，同時俄軍的襲擊行動仍對烏克蘭平民造成嚴重威脅。雙方交火的不斷升級，使戰區及非戰區的安全形勢日益緊張，尤其是涉及公共交通及民生設施的攻擊，引發烏克蘭社會的高度關注與安全擔憂。

On October 4, the General Staff of the Armed Forces of Ukraine reported that Ukrainian forces carried out a strike on the Kirishi Oil Refinery in Kirishi, Leningrad Oblast, Russia. The report stated that explosions and fires were observed at the site, though the exact impact of the strike was still being verified. The Kirishi refinery is one of the largest oil-processing facilities in Russia, with an annual refining capacity of 18.4 million tons of crude oil, making this attack a significant strike against Russian energy infrastructure.

In addition, Ukrainian forces targeted several other Russian military assets across different fronts. In the Onega Lake area of the Russian Republic of Karelia, a small missile boat, the Buyan-M, was reportedly struck, with the extent of the damage still under assessment. In Kursk Oblast, Ukrainian forces destroyed a Russian “Accordion” radar station and a transport-loading vehicle associated with the Iskander tactical missile system. Ukrainian troops also carried out a strike against the headquarters of Russia’s 8th Army Group stationed in Donetsk Oblast, hitting the target, though the exact results are still being confirmed. As of now, Russia has not publicly responded to these attacks.

Meanwhile, on the domestic front in Ukraine, related incidents occurred as well. According to reports, the military administration head of Sumy Oblast, Oleh Hryhorov, stated on social media that a passenger train traveling from Shostka to Kyiv was attacked by Russian forces on October 4. Ukrainian media reported that the strike resulted in approximately 30 people being injured. Hryhorov indicated that some passengers were wounded, and medical personnel along with Ukraine’s State Emergency Service were providing on-site assistance, though he did not disclose further details about the number of injuries or specifics of the attack.

The National Public Broadcasting Company of Ukraine cited Oksana Tarashchuk, acting head of the Shostka district military administration, who said that the train was stationed at Shostka train station when it was struck. The attack caused the train to catch fire, and roughly 30 passengers were injured and transported to hospitals for treatment. The exact number of casualties is still being verified.

Overall, the events of October 4 demonstrate that Ukrainian forces continue to conduct precision strikes against Russian energy infrastructure, missile systems, and command centers. At the same time, Russian attacks remain a significant threat to Ukrainian civilians. The escalating exchanges highlight a growing security concern both in conflict zones and in areas not directly on the front lines, particularly when public transportation and civilian infrastructure are targeted, drawing heightened attention and concern from Ukrainian society.
