An international agreement to avert wider conflict in Ukraine was faltering on Monday, with pro-Moscow separatist gunmen showing no sign of surrendering government buildings they have seized.
U.S. and European officials say they will hold Moscow responsible and impose new economic sanctions if the separatists do not clear out of government buildings they have occupied across swathes of eastern Ukraine over the past two weeks.
Washington, which signed last week’s accord along with Moscow, Kiev and the European Union, held open the possibility of slapping sanctions on Russian President Vladimir Putin personally, but suggested no such step would be taken soon.
