Ukrainian drones struck a Rosneft oil refinery in Russia's Ryazan region early Thursday, sparking a fire, hours after President Volodymyr Zelenskyy declared that Kyiv was finished pausing attacks on Russian energy infrastructure.

Zelenskyy told the Financial Times that Ukraine's patience had run out following three days of restraint. "The block [on attacking refineries] is out. We're done," he said in the interview published Thursday.

The strike came after U.S. President Donald Trump announced an energy ceasefire between Russia and Ukraine on Sunday. Ukraine had halted attacks on Russian refineries to comply, but Russia continued striking Ukrainian power plants and other energy targets, leaving hundreds of thousands without electricity and killing more than 100 civilians in the past week.

Ryazan Governor Pavel Malkov confirmed the fire at the refinery, which supplies fuel to Moscow and accounts for a significant portion of Russia's refining capacity. Emergency services responded to the scene.

Zelenskyy expressed frustration over what he described as a withdrawal of U.S. intelligence sharing and restrictions on Starlink services used by Ukrainian forces. He linked these developments to U.S. pressure to maintain the refinery pause and criticized Washington's business dealings with Moscow.

The Ukrainian leader indicated he would consider resuming the halt only in exchange for additional U.S.-made Patriot interceptors. Russia reported intercepting Ukrainian drones overnight, while Ukraine claimed to have downed hundreds of Russian drones.

The developments mark a sharp escalation in the energy dimension of the conflict, which has already driven global diesel prices higher. Ukraine had previously targeted Russian refineries multiple times in recent months as part of its strategy to degrade Moscow's war-making capacity.
