Russian crude oil supplies to Hungary and Slovakia through the Druzhba pipeline have restarted after an outage caused by a Ukrainian attack in Russia last week.

Axar.az informs, citing TVP world, Hungarian oil company MOL and Slovakia's economy minister reported this on Thursday.

Slovak Economy Minister Denisa Sakova informed about the resumption of supplies through the Druzhba pipeline in a Facebook post.

"I hope the operations will remain stable and there will be no more attacks on energy infrastructure," Sakova said.

Hungarian Foreign Minister Peter Szijjarto said on Wednesday that shipments could resume on Thursday in test mode at lower than standard volumes.

The supplies were interrupted repeatedly last week and there had been no flows since August 21 after Ukraine struck the Unecha pumping station on the pipeline.
