Oil supplies to Slovakia via Russia's Druzhba pipeline have resumed and oil is expected to arrive to the country later on Wednesday, Slovak pipeline operator Transpetrol said.

Oil flows into Slovakia via the Druzhba pipeline were halted due to technical issues outside Slovakia. According to operator Transpetrol, operations are expected to resume later in the evening. The pipeline halt highlights the vulnerability of cross-border energy infrastructure.

Hungary’s Foreign Minister Peter Szijjartosaid Tuesday that Russian oil supplies were temporarily suspended via the Druzhba oil pipeline, a key supply route for much of central Europe, following large-scale Ukrainian drone strikes overnight.

Shipment of crude oil via the Druzhba pipeline resumed on Tuesday afternoon after a suspension following a Ukrainian drone attack on a metering station, said Hungarian foreign minister Peter Szijjarto.
