Ukraine's Defense Forces struck two targets deep inside Russia that sustain the country's war machine overnight on 14 June, hitting a strategic state fuel reserve depot and a chemical plant linked to explosives production, monitoring Telegram channels reported. The operation triggered air alerts across 28 Russian regions and flight restrictions at six airports. President Zelenskyy confirmed the strikes, calling them "long-range sanctions" against Russia's refusal to end the war.

Rosrezerv fuel depot ablaze in Rybinsk

Ukrainian strike drones hit the Kombinat Temp oil depot in the Kopayevo settlement of Rybinsk, Yaroslavl Oblast, in the early hours of 14 June, Ukrainian Telegram channel Exilenova+ reported. Russian news Telegram channel Astra confirmed the target. A massive fire broke out at the facility, sending a thick column of black smoke over the city.

The Kombinat Temp is a Federal Government Custodial Institution operated by Rosrezerv, Russia's Federal Agency for State Reserves. The depot stores untouchable strategic fuel and petroleum product reserves designated for use during wartime, large-scale crises, and national emergencies. Unlike commercial fuel depots, this facility guards reserves that Russia's military depends on as a last-resort supply, Militarnyi noted.

Astra's OSINT analysis identified the target as the Kombinat Temp. Dense smoke continued rising over the city at dawn.

Footage published after the attack showed a Liutyi-type drone striking the already-burning plant. After the fire took hold, oily droplets began falling across Rybinsk, Exilenova+ reported and shared photos. The phenomenon mirrors what happened in Perm in late April after drones torched a Transneft pumping station, and in Tuapse when an oil refinery and its depot burned.

Azot chemical plant burning in Novomoskovsk

Ukrainian drones also struck the Azot chemical plant in Novomoskovsk, Tula Oblast, roughly 350 km from the Ukrainian border. Exilenova+ first reported the attack around 02:40. Tula Oblast Governor Dmitry Milyayev claimed a fire broke out "at one of Novomoskovsk's industrial enterprises during the repulsion of a Ukrainian drone attack," without naming the Azot plant and framing it as caused by falling drone debris.

NASA's FIRMS thermal monitoring system detected an anomalous heat signature directly at the Azot facility at 03:09. Local residents filmed a large fire on the plant's grounds at dawn, contradicting the governor's attempt to minimize the strike's impact.

Astra's separate OSINT analysis found that eyewitness video of an explosion in Novomoskovsk probably showed air defense activity, while a separate Astra report confirmed the fire at the Azot chemical combine.

Zelenskyy confirms strikes, 28 regions under air alerts

President Zelenskyy wrote on Telegram on the morning of 14 June: 

"There are good results from our warriors in applying long-range sanctions on important objects on the territory of Russia and temporarily occupied territories of Ukraine."

He specified that the Security Service of Ukraine (SBU) forces struck an oil facility in Yaroslavl Oblast, "more than 700 kilometers from our state border," which was significant for the reserve of the aggressor state. Army forces hit targets in Tula Oblast, specifically the Azot enterprise "on whose operations the capacity to produce explosives depends," Zelenskyy said.

Six Russian airports restricted air traffic during the operation, and air alerts sounded across 28 Russian regions from the previous evening, according to the President. Ukrainian forces also hit Russian military logistics on temporarily occupied Ukrainian territory, he said.

"Ukraine is fulfilling its plan of long-range sanctions against Russia and designated tasks regarding midstrikes in response to Russia's refusal to end this war," Zelenskyy wrote. 

He added that Kyiv had offered Moscow "all possible negotiation formats," but the response was "only the continuation of aggression and attempts to expand it." 

"Logically, the war returns to where it came from," the President concluded.

Previous attacks on both targets

Ukrainian drones hit the same Kombinat Temp depot on 31 December 2025, triggering a large fire that destroyed several fuel tanks. SBU sources called it part of a campaign to cut Russia's petroleum supply chains.

Ukraine also struck a separate Rosrezerv facility, the Kristall depot in Engels, Saratov Oblast, on 14 November 2025. That depot stores aviation fuel for Russia's strategic bomber base.

The Azot plant in Novomoskovsk has been attacked multiple times. Drones previously hit the facility on 26 May 2026. Other chemical plants in Russia's explosives supply chain have also been targeted, including KuibyshevAzot in Tolyatti on 11 March 2026 and Tolyattiazot on 19 December 2025.
