Russian crude oil flows to Hungary and Slovakia via the Druzhba pipeline were halted on Monday, officials in Hungary and Slovakia said, with Budapest blaming a Ukrainian attack on a part of the network.

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.

Italian police have arrested a Ukrainian man suspected of coordinating the attacks on the Nord Stream pipelines in the months that followed Russia’s full-scale invasion of Ukraine.
