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.
On Wednesday, the Russian flags were removed from the buildings of Russia's trade mission in Washington and the Consulate General in San Francisco.
"The flag at the former Russian Washington, DC property was also taken down and is safely stored within the building".
"Such steps only complicate US-Russian dialogue", he said in televised remarks. "In addition to the blatant attack on the flags, the Americans do not hide the fact that they have also rummaged through the documents in the office of the Consulate General in San Francisco, even though consular archives shall be considered inviolable in accordance with the bilateral Consular Convention".
U.S. State Department officials searched the Russian general consulate in San Francisco earlier this month after Russian diplomatic staff was forced to vacate the property on Washington's orders.
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".
"We consider this incident as a desecration of the Russian state symbols", the ministry's spokeswoman Maria Zakharova said at a news briefing.
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.
The Russian Embassy in Washington has forwarded an official protest to the U.S. authorities with a demand to return Russian state symbols to their flag poles.
Earlier on Thursday, the State Duma Council chose to postpone the parliamentary delegation's visit to the U.S. due to the present circumstances, the lower house of the Russian parliament said.
He pledged that the State Department is responsible for the safety of these facilities and is maintaining them in due condition.
Nevertheless, the buildings in question still remain the property of Russian Federation, except for the office of the trade mission, which Russian Federation was renting.
