Crude oil shipments through the Druzhba pipeline have resumed, ending a suspension ordered last week due to a Ukrainian drone attack on a metering station, Hungarian Foreign Minister Peter Szijjarto announced on Tuesday afternoon, according to a Reuters report.

The resumption followed repairs by the Russian system operator to damage sustained in the attack, Szijjarto said.

Earlier on Tuesday, Ukraine said it had struck an oil refinery near Moscow and a facility in Russia's Oryol region that is part of the Druzhba pipeline system, which exports oil to Europe. Szijjarto had previously announced the suspension of crude shipments due to the attack, disrupting oil supply to European destinations. 

Slovak pipeline operator Transpetrol confirmed that oil supplies to Slovakia via Druzhba were halted Tuesday and that flows were expected to resume in the evening.

The southern strand of the Druzhba pipeline, which carries Russian oil to Europe, splits in Ukraine near the Slovak border, with one line supplying Slovakia and the Czech Republic and the other reaching Hungary.

Russia's Transneft, which operates the Druzhba pipeline within Russia, did not immediately respond to a request for comment, according to the Reuters report. 

"Explosions were ... recorded in the area of the Steel Horse linear production dispatch station (Oryol region, Russia), which manages technological processes for the Druzhba oil pipeline," Kyiv's General Staff said in a statement.

Hungary imports the majority of its crude oil through the Druzhba pipeline, which transports Russian crude via Belarus and Ukraine to Hungary and Slovakia.

Supplies via Druzhba to Czech refineries have been halted since last week. Czech refiner Unipetrol, owned by Poland's Orlen, said late Monday that it had begun drawing oil from state reserves to maintain production at its refineries.
