Russia has resumed its aerial pounding of Ukraine’s power grid and Kyiv’s forces again targeted Russian oil facilities with cross-border drone strikes, officials said.

With no major changes reported along the 600-mile front line, where a recent push by the Kremlin’s forces in eastern and north-eastern Ukraine has made only incremental gains, both sides in the war have taken aim at distant infrastructure targets.

In its seventh major attack on Ukrainian power plants since Moscow intensified energy infrastructure attacks three months ago, Russia fired nine missiles and 27 Shahed drones at energy facilities and critical infrastructure in central and eastern Ukraine, the Ukrainian air force said.

Air defences intercepted all the drones and five cruise missiles, it said.

The attack hit power structures in the Donetsk, Dnipropetrovsk, Kyiv and Vinnytsia regions of Ukraine, according to national power company Ukrenergo.

Private energy company DTEK said one of its power plants was hit in the overnight attack but did not specify its location. Three company employees were injured and the plant’s equipment was severely damaged, DTEK said on social media.

Among the most damaging recent strikes on Ukraine’s energy supply were an April barrage that damaged Kyiv’s largest thermal power plant and a massive attack on May 8 that targeted power generation and transmission facilities in several regions.

Rolling blackouts have affected Ukrainian households and industry.

In Russia, meanwhile, authorities in two regions reported fires at oil storage depots after drone attacks, two days after a Ukrainian strike started a huge blaze at another refinery.

Ukraine has in recent months stepped up aerial assaults on Russian soil, targeting refineries and oil terminals in an effort to disrupt the Kremlin’s war machine.

Murat Kumpilov, head of Russia’s Adygea region, said a Ukrainian drone attack sparked a fire at an oil depot in the town of Enem that was later extinguished.

The head of the Tambov region, Maxim Yegorov, said an oil reservoir went ablaze at an oil depot there.

Krasnodar region governor Veniamin Kondratyev said a drone hit a private house in the town of Slavyansk, killing a woman.

Russia’s Defence Ministry said air defences downed 15 Ukrainian drones over three regions but did not mention any damage.
