Germany, which sits at the northern end of the pipeline and has also continued to receive oil from Russia, was not affected by the interruption, Transneft said.
Since invading Ukraine in February, President Vladimir V. Putin of Russia has shown that he is willing to use his control of the energy spigot as leverage over Europe. He has also demonstrated his knack for keeping his adversaries off-balance by sending mixed signals and trying to play Western allies against one another.
In the spring, Russia cut deliveries of natural gas to several European countries, starting with Bulgaria and Poland, then adding Finland. In June, on the day that the leaders of France, Germany and Italy visited Kyiv, those countries reported a shortfall of deliveries of Russian gas, as did Austria and the Czech Republic.
Flows through the Nord Stream 1 pipeline to Germany, Europe’s main consumer of Russian gas, have been slashed by 60 percent and then by 80 percent. Moscow blamed the disruption on a pipeline component that was being refurbished by a German company at a factory in Canada, causing tensions between Ottawa and Berlin.
