In July, Moscow wanted 455 to reduce number of diplomatic and technical personnel working in Russian Federation to United States after tension of relations between two countries, 60 per cent.
"As current geopolitical realities become tougher, when the United States start an unprecedented enlargement of anti-Russian sanctions and fixed this move in the form of a law it would be very logical from our side to introduce some counter-measures", he added.
She said that agents of USA special services removed Russian flags from the Russian trade mission in Washington and the Consulate General in San Francisco, which were seized by the US authorities in September in a series of tit-for-tat actions that form part of the spat between the two countries.
Russia's Foreign Ministry has issued a statement of protest after American authorities reportedly took down several Russian flags from a seized consulate in San Francisco. The US set a deadline of October 1 for diplomats from the consulate general in San Francisco to pack their belongings.
The reason why Moscow has fully downloaded USA personnel to 455 is that this figure was also number of Russian diplomatic personnel in United States.
According to Zakharova, the statement from the US State Department which said that no one deprived Russian Federation of the rights for those buildings was "outright hypocrisy".
He stressed that it had been done with due respect to the Russian national symbols.
Russian Federation has drastically scaled down the US diplomatic staff in Russian Federation to 455 people and seized a USA dacha and a warehouse in Moscow in retaliation to Washington's actions.
"We consider this as an extremely unfriendly step", the embassy said.
"The flags at the former Russian consular properties in San Francisco were respectfully lowered and are safely stored within each of the buildings", the official said on Wednesday. US State Department officials, in turn, said that employees of the department made the round of the Russian premises after all diplomats had left them. Besides, they demanded that the Consulate General in San Francisco should be closed and the consul general's residence emptied. However, the Diplomatic Security Service of the US State Department and its foreign missions department have taken the objects of the Russian diplomatic mission under control.
