Repeated Ukrainian military strikes on infrastructure have underscored Hungary’s heavy dependence on Druzhba. Currently, 58 percent of the country’s oil — about 5.7 million tons annually — arrives via the line to the refineries in Szazhalombatta and Bratislava.

Hungarian Foreign Minister Péter Szijjártó has said that the Russian Druzhba oil pipeline has resumed operations and expressed hope that Ukraine will no longer conduct new attacks on it.

Russian oil supplies to Hungary and Slovakia could be suspended for at least five days after a Ukrainian strike on a facility in Russia, Hungarian and Slovakian officials said on Friday, in a widening of the fallout of Russia's war in Ukraine.
