A sharp energy dispute has erupted between Slovakia and Ukraine, with Prime Minister Robert Fico threatening to suspend electricity supplies if oil transit through the Druzhba pipeline is not restored. The row follows reported disruptions by Ukrtransnafta affecting Slovakia and Hungary. Hungarian Foreign Minister Peter Szijjártó accused President Volodymyr Zelenskyy of blocking supplies for political leverage. Fico claims Slovakia has already suffered major financial losses and warned Ukraine risks losing European support. The standoff underscores deepening cracks within the European Union over wartime energy politics.
