According to Russia, gas deliveries via Nord Stream 1 cannot be resumed until further notice due to the sanctions. "We don't know how the repair work will be carried out because the sanctions prevent it," Kremlin spokesman Dmitry Peskov said at the economic forum in Vladivostok, according to the Interfax news agency.

The Kremlin states "with regret that the responsibility for the situation lies entirely with the European states and the states that have introduced sanctions against our country".

Peskow spoke of a "potentially dangerous situation for the company" as a result of the oil leak from a turbine. For this reason, the turbine - and thus the pipeline - cannot be put back into service without prior repair work. However, Gazprom remains a reliable gas supplier.

Gazprom tied the delivery stop on Monday to an alleged design flaw in the turbine supplied by Siemens Energy. Due to the risk of fire from the oil spill, continued operation was forbidden.

Siemens Energy has rejected this representation: "Such leaks do not normally affect the operation of a turbine and can be sealed on site," said a spokesman. The federal government considers the technical problems with the pipeline to be a pretext and denies Russia the status of a reliable gas supplier.

Federal Minister of Economics Robert Habeck assumes that Russia will no longer supply gas to Europe via Nord Stream 1. "There's still a bit of gas coming through the Ukraine pipeline, but Nord Stream 1 being reopened isn't one of the scenarios I'm assuming," the Greens politician said on Monday evening on ZDF's "heute journal".
