Germany's top energy regulator called consumers and industry to scale back gas consumption due to the current cuts in Russian gas on Thursday.

'The current cuts in Russian gas and supply can put us all - consumers and industry - in a very serious situation,' Klaus Müller, the head of the Bundesnetzagentur agency wrote on Twitter.

'We must avoid this through gas savings and storage, as long as we can,' he warned.

Müeller's remarks came after a decline in Russian gas deliveries to Germany via Nord Stream pipeline. Both Uniper SE and RWE AG said that they received less gas from Russia.

Natural gas shipments through the Nord Stream pipeline will drop by 40% due to technical problems, Russian energy company Gazprom said on Tuesday.

Gazprom said that some of the gas compressors sent to the German Siemens company for maintenance have not turned yet.

Nord Stream is known as one of the important lines carrying Russian gas to Europe, as well as the Yamal-Europe pipeline and the pipelines in Ukraine.
