The Russian government slammed the Trump administration's decision to close three diplomatic missions in the United States as "outrageous" and said the American government "seized" the buildings.
Secretary of State Rex Tillerson gave the Russians three days to move out of buildings in New York, San Francisco, and Washington, D.C. last week. The move was retaliation for the Russian government cutting the amount of staff at U.S. diplomatic missions in Russia.
"This outrageous move is in line with actual expropriation of Russia-owned countryside residences near Washington, D.C. and New York last December. At present, the US special services supported by armed police are in control of the seized buildings," the Russian foreign ministry said in a statement.
"We treat these developments as a blatantly hostile act, a grave violation by Washington of international law, including the Vienna Conventions on Diplomatic and Consular Relations and the bilateral Convention on Consular Relations."
"We urge the US authorities to come to their senses and to immediately return the Russian diplomatic facilities. Otherwise the USA will bear the total blame for the ongoing degradation of the relations between our countries, on which the current condition of the global stability and international security largely depends."
Relations between the U.S. and Russia have been at a low point in recent months as the Trump administration has found diplomacy with the Kremlin as difficult as former President Barack Obama's diplomats did.
The tit-for-tat measures started after Obama closed down Kremlin-owned buildings near Washington, D.C., in retaliation for Russian meddling in the 2016 presidential election. It's the strongly held opinion of the American intelligence community that the Kremlin ordered an influence campaign on the 2016 presidential election to harm Hillary Clinton's campaign.
