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.

Russia has resumed delivery of its oil to Slovakia and Hungary following repairs to a pumping station on the Druzhba export pipeline that was attacked by Ukraine on Sunday.
