"Currently, only one gas processing unit is working at the Portovaya compressor station at the Nord Stream 1 gas pipeline," Gazprom Deputy Chief Executive Vitaly Markelov said on Wednesday, as reported by Reuters.

"Other units require maintenance or servicing by Siemens," Markelov said and noted that they haven't received the engine from Siemens.

"There are sanctions risks for engines," he further added. "Siemens is not working to solve problems."
