Ukraine said it carried out long-range strikes on military and energy targets deep inside Russia, including a factory in Cheboksary, a refinery in Samara and oil infrastructure in Vladimir region. Russian regional officials confirmed damage and injuries, and reporting said a major Samara refinery halted processing after the attack.

Ukraine said it carried out a coordinated package of long-range strikes on military and energy targets deep inside Russia, hitting sites in Cheboksary, Samara and Vladimir region.

President Volodymyr Zelenskyy said the attacks used FP-5 Flamingo missiles and drones. Reporting from AP and The Guardian said the strikes were part of Ukraine's effort to raise the cost of Russia's war by hitting military-industrial and fuel infrastructure far from the front line.

Targets hit

AP reported that Ukraine struck a military factory in Cheboksary, a refinery in Samara and oil infrastructure in Vladimir region on Wednesday, June 10. Zelenskyy said the Cheboksary target was a military plant supplying components for Russian drones and missiles.

The Guardian later reported local confirmation in Chuvashiya and Samara. Oleg Nikolayev, the head of Chuvashiya, confirmed the Cheboksary attack, while Samara governor Vyacheslav Fedorishchev said industrial plants were damaged and three people were injured.

Refinery outage and damage claims

The Guardian, citing Reuters and industry sources, reported that Rosneft's Kuibyshev refinery in Samara halted oil processing after a drone attack. That refinery is part of a strategically important fuel supply network for Russia.

Russia's Defense Ministry said 326 Ukrainian drones were shot down overnight, AP reported. The ministry's account did not address the specific damage claims reported by Ukrainian and regional officials.

Why it matters

The strikes underline Ukraine's ability to hit industrial and energy targets far beyond the battlefield. Cheboksary is more than 900 kilometers from the front line, according to the reporting, making it one of the deeper confirmed strikes in the latest wave.

The attacks also fit a broader pattern in the war: Ukraine has increasingly targeted Russian refining and military production capacity in an effort to disrupt supply chains and raise operational costs for Moscow.

What remains unclear

Full damage assessments were not immediately available for the targeted sites, and it was not clear how long the Kuibyshev refinery would remain offline, if at all. It was also not immediately possible to separate the effect of missiles and drones at each target.

Further evidence from Ukraine could clarify the exact role of the Flamingo missiles in each strike, while Russian authorities are likely to continue releasing their own damage assessments.
