Stop targeting Russia's oil refineries: Trump to Ukraine's Zelenskyy

US President Trump told Ukrainian President Volodymyr Zelenskyy to halt strikes on Russia’s oil refineries as average US diesel prices soared past $6 a gallon. “He has to stop knocking out diesel fuel in Russia. There are plenty of other targets. Don’t hit diesel fuel, because that’s hurting the world,” Trump said. Ukraine says Russia’s oil industry funds the war.
