Ukraine says its forces have hit two of Russia’s major oil refineries in their latest long-range strikes. Officials say the attacks are part of Kyiv's ongoing pressure on Moscow. The strikes have targeted Russian oil facilities for months, causing a fuel crisis that embarrasses the Kremlin. Fires broke out at a Lukoil refinery in Russia’s Perm region and another in Ryazan. The refineries are crucial for Russia's military and government revenue. The attacks came after President Volodymyr Zelenskyy visited Washington for talks with President Donald Trump, seeking more U.S. support for Ukraine.
