Russian attacks on Ukraine killed one person and wounded at least 26 more on Friday, according to local officials, as Ukrainian drone strikes targeted major oil refineries in Russia’s Samara region, escalating a months-long campaign against Russian energy infrastructure.

The civilian death occurred in Mykolaivka in Ukraine’s eastern Donetsk region, regional leader Vadym Filashkin said on social media. Attacks also damaged port infrastructure in the Black Sea city of Odesa.

Ukrainian drones struck major oil refineries in Novokuibyshevsk and Syzran in Russia’s Samara region on Friday, the General Staff of Ukraine’s Armed Forces said. The strikes sparked fires at the Vystosk oil terminal in Russia’s northwestern Leningrad region and an oil refinery in the southern Krasnodar region, Ukrainian officials said. Russian officials later confirmed the blazes.

The strikes reflect Ukraine’s escalating strategy of degrading Russia’s oil sector, a campaign that has intensified since the Trump administration extended a temporary waiver on sanctions against Russian oil to ease global supply constraints. The policy has drawn Kyiv’s protests, with Ukrainian officials warning that additional Russian oil revenue will fund new weapons to intensify attacks.

Russian forces attacked civilian areas across Ukraine on Friday, killing one person and wounding at least 26 more, according to local officials, as Ukrainian drones struck major oil refineries in Russia’s Samara region, part of an expanding campaign to disrupt Moscow’s energy sector.

The casualty occurred in Mykolaivka, in Ukraine’s eastern Donetsk region, regional leader Vadym Filashkin said on social media. Attacks also damaged port infrastructure in the Black Sea port city of Odesa.

Russia’s Ministry of Defense claimed it destroyed 258 Ukrainian drones overnight across 16 Russian regions, as well as over the annexed Crimean peninsula and the Black and Azov seas.

Ukraine’s Escalating Oil Campaign

Ukraine has repeatedly targeted Russian oil facilities in recent months. The campaign intensified after the Trump administration extended a temporary waiver on sanctions against Russian oil shipments Friday for an additional 30 days to ease global supply constraints.

Ukrainian officials protested the extension, warning that additional revenue from Russian oil sales will finance new weapons systems for attacks on Ukraine. The disagreement has created friction between Kyiv and Washington as the war continues without resolution.

Ukraine’s drone and missile industry has developed significant capability in recent years. The country’s conventional air defense, however, remains constrained by a shortage of sophisticated systems. U.S. Patriot batteries provide some protection, but Ukrainian officials have repeatedly stressed the critical need for additional air defense resources.

Air Defense as Diplomatic Priority

Thursday brought one of Russia’s most intense aerial attacks in recent weeks, killing at least 16 people and wounding more than 100 others across Ukrainian civilian areas, according to Ukrainian authorities. The scale underscored the urgency of Ukraine’s push for stronger air defenses.

Air defense has been a primary focus for Kyiv since Russia’s invasion began more than four years ago. It has become central to Ukrainian diplomatic efforts as peace negotiations remain stalled.

President Volodymyr Zelenskyy traveled to Germany, Norway, and Italy earlier this week to press allied governments for air defense support. On Saturday at the Antalya Diplomatic Forum, Ukrainian Foreign Minister Andrii Sybiha said he discussed “steps to enhance protection” with NATO Deputy Secretary General Radmila Shekerinska.

“Amid intensified Russian air terror, our priority number one is to strengthen our air defense,” Sybiha said.
