BERLIN (AP) — Russian energy giant Gazprom says it can’t resume the supply of natural gas through a key pipeline to Germany for now because of what it said was a need for urgent maintenance work. Friday’s announcement came just hours before Gazprom was due to resume deliveries. The Russian state-run energy company had shut down the Nord Stream 1 pipeline on Wednesday for what it said would be three days of work. It said in a social media post Friday evening that it had identified “malfunctions” of a turbine and said the pipeline would not work unless those were eliminated.
