Ukraine Strikes Russian Chemical Plant and Oil Depot 700km Inside Russia

Ukrainian forces conducted deep-strike operations against Russian territory overnight on June 13–14, hitting a chemical plant in the Tula region and an oil storage facility in the Yaroslavl region — both well over 700 kilometers from Ukraine's borders — Ukrainian President Volodymyr Zelensky confirmed on June 14.

The Security Service of Ukraine (SBU) struck an oil facility in Russia's Yaroslavl Oblast that Ukrainian officials said was integral to Russia's strategic fuel reserves. The Yaroslavl facility is one of the deepest targets Ukraine has struck since the full-scale invasion began.

Azot Chemical Plant in Tula Hit

The second target was the Azot enterprise in Novomoskovsk, Tula Oblast. The plant produces chemicals used in the manufacture of explosives and fertilisers, making it a strategic military-industrial target. A major fire broke out at the facility following the strike, with footage shared on social media appearing to show thick smoke rising from the complex.

Tula Oblast Governor Dmitry Milyayev acknowledged that the area was targeted overnight, saying that "fragments of downed Ukrainian drones fell onto the territory of one of the industrial enterprises in Novomoskovsk," without confirming the extent of the damage.

Strategic Significance

The strikes are part of Ukraine's sustained campaign to hit military-industrial targets deep inside Russia, disrupting the production and logistics chains that feed the war effort. Ukraine has increasingly targeted oil infrastructure, chemical plants, and military-related industrial facilities in Russian regions including Saratov, Ryazan, and now Tula and Yaroslavl.

These deep strikes — carried out using Ukrainian-made long-range drones — serve a dual purpose: degrading Russia's capacity to sustain its military campaign and creating domestic pressure inside Russia on the Kremlin. Ukrainian officials have consistently said the strikes target exclusively military-linked facilities.

The operations took place on the same night that Russia launched a massive barrage of 611 drones and 70 missiles against Ukrainian cities, setting the historic Kyiv Pechersk Lavra ablaze and killing five rescuers in Kharkiv — indicating that both sides continue to pursue offensive operations simultaneously rather than signalling any de-escalation.
