Ukraine has widened its campaign against Russian energy assets, striking both the Novoshakhtinsk oil refinery in Rostov Oblast and the Unecha pumping station on the Europe-bound Druzhba pipeline. Video from the overnight raid showed several process units at Novoshakhtinsk, the largest refinery in southern Russia, engulfed in flames after a series of explosions. Hours later, Ukraine’s unmanned systems hit Unecha in Russia’s Bryansk region, forcing a shutdown of the Druzhba link that carries crude to Central Europe. Hungarian and Slovak officials said deliveries have been suspended for at least five days, marking the second stoppage this week. Hungarian Foreign Minister Peter Szijjarto called the latest strike “another attack against our energy security,” while he and his Slovak counterpart, Juraj Blanar, urged the European Commission to guarantee alternative supplies. The pipeline disruption underscores the lingering dependence of Hungary and Slovakia on Russian crude even as the European Union seeks to phase out such imports by 2027. The cross-border attacks highlight an escalating duel over energy infrastructure: Kyiv is targeting facilities that finance Moscow’s war effort, while Russia continues to bombard Ukrainian gas and heating installations. The flare-up complicates U.S.-brokered efforts to negotiate a cease-fire and raises fresh questions about Europe’s supply resilience heading into winter.
