Europe is investigating what caused three pipelines in the Nord Stream network to burst in an act of suspected sabotage near Swedish and Danish waters that Moscow quickly sought to pin on the West, suggesting the United States stood to gain."The coast guard is responsible for the mission, but we are supporting them with units," a spokesperson for the Swedish navy, Jimmie Adamsson, told Reuters.Kremlin-controlled Gazprom (GAZP.MM) also said flows could resume at the last remaining intact pipeline in the Nord Stream 2 network, a suggestion likely to be rebuffed given Europe blocked Nord Stream 2 on the eve of Russia's invasion of Ukraine in February."If a decision is made to start deliveries through Nord Stream 2's line B, natural gas will be pumped into the pipeline after the integrity of the system has been checked and verified by supervisory authorities," Gazprom said.Eni, the biggest importer of Russian gas in Italy, at the weekend said Russia had halted all gas flows through the Tarvisio entry point, though its chief executive on Monday blamed the halt on short-term technical issues."
