“If they do not recognize some referendums, do not recognize votes, countries and territories, these are double standards,” RIA Novosti quoted her as saying.

Earlier, State Department spokesman Ned Price said that the United States considers the results of the referendums on the entry of the Donetsk and Lugansk People's Republics, as well as the Zaporozhye and Kherson regions into Russia, "completely fabricated" and plans to introduce new anti-Russian sanctions in the near future.

EU foreign policy spokesman Peter Stano said the EU could impose sanctions against Europeans who acted as observers in referendums.
