WASHINGTON (AP) -- A Pentagon spokesman says if Russian troops were really pulling back from the border with Ukraine, then "we would know." And he says that doesn't seem to be happening.
Russian President Vladimir Putin told diplomats today that his troops have been moved away from the border region. Russia has had about 40,000 troops positioned on Ukraine's border for several weeks.
Putin also called on Ukraine's military to stop its operations against pro-Russia activists who have seized government buildings and police stations in at least a dozen towns in eastern Ukraine.
And he urged insurgents in southeastern Ukraine to postpone their planned Sunday referendum on autonomy.
The White House says the referendum should be canceled, not postponed.
