Ukraine’s strike on the Unecha pumping station of the Druzhba oil pipeline in Russia’s Bryansk region has halted crude deliveries to Hungary and Slovakia for several days, triggering sharp protests from both governments and a fresh political dispute over Ukraine’s path to the European Union.
Slovakia’s economy minister, Denisa Saková, said flows could resume “as soon as Monday” under a best-case scenario, after an outage initially estimated at four to five days. She added that domestic supply was not at risk given Slovakia’s mandatory 90-day emergency stocks.
Budapest and Bratislava have formally asked the European Commission to help safeguard supply security. Hungary’s foreign minister, Péter Szijjártó, condemned the attacks, while Slovakia’s foreign minister, Juraj Blanár, told his Ukrainian counterpart that any prolonged interruption on Druzhba could also affect fuel shipments from Slovakia to Ukraine.
The exchange has spilled beyond the EU. A letter from Hungarian Prime Minister Viktor Orbán to U.S. President Donald Trump complaining about the pipeline strike prompted a handwritten reply in which Trump said he was “very angry”. The episode added diplomatic weight to Hungarian and Slovak calls for action after the attack.
EU law currently permits Hungary and Slovakia to keep importing Russian crude by pipeline under exemptions agreed in the sixth sanctions package in June 2022, while the bloc phases out Russian fossil fuels by end-2027. Both countries remain connected to the southern arm of Druzhba and have argued they cannot yet rely fully on alternatives. The Commission, for its part, notes that member states must hold at least 90 days of oil stocks, a buffer intended to absorb short-term supply shocks such as the present outage.
Analysts have long debated the extent to which the Adriatic (JANAF/Adria) route via Croatia could backstop supply to refineries in Hungary and Slovakia. While Budapest and Bratislava highlight constraints and costs on that line, independent studies suggest the corridor could replace a substantial share of Russian barrels over time with appropriate investments and scheduling.
The pipeline incident has also reignited political tensions around Ukraine’s EU accession track. Since early 2025, Hungary has blocked the opening of the first negotiation “cluster”, citing concerns ranging from minority rights to wartime risks. Brussels and several capitals say there are “no objective reasons” to delay the technical launch, and have explored procedural workarounds to keep momentum. The stand-off has raised questions over whether Moldova, which is negotiating in parallel, could move one step ahead pending a resolution of the dispute with Budapest.
Statements from Hungarian officials in July reiterated opposition to Ukraine’s EU membership on the grounds that a country at war could import security risks into the Union. Orbán has described Ukraine as a prospective “buffer” and argued instead for looser forms of cooperation. Kyiv and its backers reject that characterisation, pointing to security guarantees being developed with NATO allies and to accession as part of a long-term stabilisation strategy.
For now, the immediate market impact appears contained. Reuters reported that Slovakia’s 90-day stocks and similar obligations across the EU mitigate near-term risks, while the Commission has said it is in contact with capitals and sees no threat to the bloc’s overall energy security at this stage.
