“This is a provocation, gross interference in the affairs of our country, an attempt to increase the degree of public tension,” he told RIA Novosti.

Earlier, the US Embassy in Russia called on its citizens, as well as persons with dual citizenship, to refrain from traveling to Russia due to the “unpredictable consequences” of the conflict in Ukraine, and those who are already on its territory to urgently leave the country.

On February 7, the US Embassy was handed a note demanding to stop interfering in Russia's domestic affairs.
