effectively stopping oil deliveries to Slovakia and Hungary. Hungary on Monday made a thinly-veiled threat to cut off electricity supplies to Ukraine as the diplomatic row over damage to the Druzhba pipeline escalates. The fresh war of words erupted last week after a key distribution station of the Druzhba oil pipeline in Russia’s Bryansk region was damaged in a Ukrainian drone strike, temporarily halting oil flows to Hungary and Slovakia. Ukraine carried out a second strike on the pipeline on Monday, this time targeting the Nikolskoye oil pumping station in Russia's Tambov region. Hungarian Foreign Minister Péter Szijjártó has criticised the Ukrainian authorities for carrying out the strikes on the pipeline, describing them as "outrageous and unacceptable" and writing that "whoever attacks our energy security is, in fact, attacking our sovereignty".
