Oil is once again flowing to Hungary and Slovakia via the Druzhba pipeline, officials from both countries said late on Tuesday, after a Ukrainian drone strike on an oil pumping station in Russia's Tambov region halted supplies.

Ukrainian Foreign Minister Andrii Sybiha neither confirmed nor denied the account of the latest attack but wrote on X that Hungary "can now send complaints and threats" to Moscow, not Kyiv.

Russian oil deliveries to the European Union through the Druzhba pipeline have resumed, days after a Ukrainian strike on the line’s infrastructure brought shipments to a halt. Officials in Slovakia and Hungary confirmed the restoration of flows this week.
