Former U.S. President Donald Trump again sharply criticized Ukrainian President Volodymyr Zelenskyy, calling him "tougher to deal with than Russian President Vladimir Putin." Trump stated on Thursday evening that Ukraine's renewed attacks on Russian oil refineries were a "disgrace," arguing that the actions have driven up global oil prices. Zelenskyy sought EU support in Brussels on Friday, where European Commission President Ursula von der Leyen stated that despite Trump's call for a ceasefire, Russia has not complied, and therefore the EU will increase sanctions against Russia. Trump's dissatisfaction with Ukraine's continued attacks on refineries follows a previous U.S. announcement of a deal to import diesel from Russia to lower fuel prices.
