headlines: Seeking Leverage Over Europe, Putin Says Russian Gas Flow Will Resume
articles: BERLIN — When the main natural gas artery between Russia and Germany, the Nord Stream 1 pipeline, was taken off-line last week for 10 days of scheduled maintenance, European leaders began bracing for the possibility that President Vladimir V. Putin of Russia would not switch it back on as retaliation for opposing Moscow’s invasion of Ukraine.
  
  But Mr. Putin has suggested that the gas will resume flowing to Europe after the work on the pipeline — controlled by Russia’s state-owned energy giant Gazprom — finishes on Thursday, though he warned that supplies might be further curtailed.
  
  The European Commission called on the bloc’s 27 members to immediately begin taking steps to reduce gas consumption by 15 percent. “Russia is blackmailing us. Russia is using energy as a weapon,” Ursula von der Leyen, president of the commission, told reporters in Brussels on Wednesday.
