German Chancellor Angela Merkel and the new European Commission president said there was no prospect in sight of scaling back sanctions on Russia, maintaining a tough stance after Moscow embraced the results of a separatist election in eastern Ukraine. Ms. Merkel said in Berlin on Wednesday that the European Union should consider expanding its sanctions list to include the winners of Sunday’s local voting. The EU, Kiev and the U.S. have refused to recognize the elections and said that Russia’s refusal to condemnthem are a breach of a September cease-fire.
