Ukraine says its forces hit major Russian oil refining facilities overnight, in a strike that comes hours after President Volodymyr Zelenskiy meets Donald Trump in Washington. Multiple reports cite Ukrainian officials as saying the attack targets one of Russia’s largest refineries. One outlet specifies the Ryazan refinery and describes it as having a capacity of about 17 million tonnes of oil per year, with production including gasoline, diesel fuel and aviation fuel, among other petroleum products. Another report, citing AP, says Ukrainian forces hit two major Russian oil refineries in the same broader operation. The incidents are described as starting fires and intensifying pressure on Moscow. In parallel, Zelenskiy publicly characterizes his Washington meeting with Trump as “good,” according to some reports, framing the diplomatic element as part of a wider effort that includes military and economic pressure. Russian officials and any damage assessments are not detailed in the provided summaries, and the reports focus primarily on Ukraine’s claims regarding the timing, targets, and intended impact.
