Ukraine resumes strikes on Russian oil refineries

On Sunday, Russian strikes left hundreds of thousands of Ukrainian households without power, according to President Volodymyr Zelensky. The strikes targeted power infrastructure in four Ukrainian regions, according to the Ukrainian president. Zelensky attributed the high intensity of the strikes to Russia's efforts to exploit the limited number of ballistic missile interceptors available.

In response, Ukraine launched drone attacks on Russian facilities, including the Kamensky plant in Russia's Rostov region, which is involved in the manufacture of Russian missiles, according to Ukrainian officials.

Meanwhile, in Nizhny Novgorod region, a large-scale Ukrainian drone attack caused significant damage to an industrial facility, though the specific site was not identified by the governor of the region, Gleb Nikitin. The Norsi oil refinery, one of Russia's largest, is located in the region. Russia's defense ministry reported downing 235 Ukrainian drones over Russian regions overnight.

However, the air force stated that dozens of Russian drones remained in the air as of Sunday morning, with dozens of additional alerts issued in the capital Kyiv since midnight.

The governor of Ternopil region in western Ukraine, Taras Pastukh, reported that a Russian attack on infrastructure in a town had knocked out power to localities, and emergency crews were working to restore it. Despite a six-day local ceasefire that ended on the final day, fighting continued along the front line, and both sides maintained long-range air attacks.

Ukraine has accused Russia of targeting energy targets, including its power grid, while Russia denies these claims and asserts that Ukrainian strikes on Russian refineries are causing global fuel market imbalances and affecting prices.
