A series of long-range Ukrainian attacks hit targets deep inside Russia on Wednesday (June 10, 2026), part of Kyiv's efforts to raise the costs of the war for the Kremlin by striking energy facilities and military industries.

Ukrainian President Volodymyr Zelenskyy said his country's forces struck several military and energy infrastructure sites, including a military factory that he said supplied components for Russian drones and missiles.

In a post on social media, Mr. Zelenskyy said Ukrainian FP-5 Flamingo long-range missiles had hit the facility in Cheboksary, located in the Chuvashiya region more than 900 kilometres from the front line.

Russia's Defence Ministry said that air defences downed 326 Ukrainian drones overnight. Oleg Nikolayev, the head of Chuvashiya, confirmed the missile attack but didn't give details. The Astra online news outlet reported that the Ukrainian strike hit the VNIIR-Progress plant that produces antennas for drones.

Mr. Zelenskyy also said Ukrainian forces struck a refinery in Russia's Samara region, where Gov. Vyacheslav Fedorishchev said that several industrial plants were damaged by drone strikes and three people were injured.

Mr. Fedorishchev didn't name the facilities that were damaged, but Astra carried images of a large fire at the Samara refinery.

Mr. Zelenskyy added that Ukraine's Security Service (SBU) had also targeted two oil infrastructure facilities in Russia's Vladimir region, about 700 kilometres from the front line.

In Russia-occupied Crimea, a Ukrainian drone hit the building housing a huge panorama painting depicting the defence of the city during the 19th century Crimean War. Mikhail Razvozhayev, the Kremlin-appointed head of Sevastopol, said the painting by artist Franz Rubo was effectively destroyed.

The more than 1,000-kilometre front line in the four-year war has remained largely static as swarms of drones hinder advances, and both sides have increasingly relied on long-range strikes.

The increasingly deep and audacious Ukrainian strikes have defied Russia's President Vladimir Putin's claim that Moscow is winning the war, now in its fifth year.

Last week, Mr. Putin vowed to strengthen Russia's air defences after Ukrainian attacks set ablaze an oil terminal in St. Petersburg and also hit a nearby naval base, casting a cloud over a showcase economic forum in his hometown.

The attacks on St. Petersburg came as another embarrassment for the Russian leader, weeks after he pruned back an annual Victory Day parade in Moscow because of fears of Ukrainian drone attacks.

Ukraine's Air Force says air defences downed 181 of 207 Russian drones. A barrage of 26 drones struck Kharkiv early Wednesday (June 10), injuring at least four people, according to regional administration head Oleh Syniehubov. He said one person was killed and 15 others were injured in the region over the past 24 hours.

In the Zaporizhzhia region, 10 people were injured overnight in a series of Russian aerial attacks, according to regional head Ivan Fedorov.

In Odesa, a mother and two children, aged 8 and 10, required medical attention after Russian drones damaged two residential buildings, according to regional administration head Oleh Kiper.

Ukraine has secured commitments for additional air defence systems and ammunition following Mr. Zelenskyy's recent visits to London and Tallinn, said Foreign Ministry spokesperson Heorhii Tykhyi.

Speaking at a briefing, Mr. Tykhyi said Ukraine had “found” several additional air defence systems and munitions but declined to identify the countries that had agreed to provide them.

He said Kyiv also was working to secure financing to purchase the equipment and that part of the necessary funding had already been allocated.

Mr. Tykhyi added that Ukraine was in talks to obtain interceptor missiles nearing the end of their shelf life, arguing that they could still be provided to Ukraine instead of being disposed of after expiring.
