Ukraine says it carries out long-range strikes on Russia’s oil infrastructure hours after President Volodymyr Zelensky meets Donald Trump in Washington. Multiple outlets, including those citing Ukrainian statements, report that Ukraine hits major refineries in Russia overnight, described as among the country’s largest. One outlet specifies a fire at the Ryazan refinery and says its annual capacity is about 17 million tonnes, producing fuels including gasoline, diesel and aviation fuel. Other reporting says Ukrainian forces hit two major Russian refineries. The attacks are presented in the sources as part of Kyiv’s broader strategy to increase economic and military pressure on Moscow, while also pairing the strikes with heightened diplomatic efforts following the Zelensky–Trump meeting. Zelensky is also reported to praise the encounter as a “good meeting” in Washington. The accounts do not provide independent confirmation of the strikes’ full impact beyond Ukraine’s claims, but they consistently link the timing of the reported attacks to the period immediately after the U.S. meeting.
