Russia's Foreign Ministry has condemned the U.S. decision to seize three Russian diplomatic facilities as a "blatantly hostile act", urging Washington to immediately reverse the call or "bear the total blame" for worsening diplomatic ties.
The U.S. ordered the closure of the Russian consulate in San Francisco on Saturday, as well as two trade offices in New York and Washington. The State Department order, given in late August, followed Moscow's decision to cut America's diplomatic presence in Russia.
Diplomats from Moscow were working to vacate the properties over the weekend.
"We treat these developments as a blatantly hostile act, a grave violation by Washington of international law," the Russian Foreign Ministry said in a statement on its website on Sunday.
"We urge the U.S. authorities to come to their senses and to immediately return the Russian diplomatic facilities. Otherwise the U.S. will bear the total blame for the ongoing degradation of the relations between our countries," the ministry added.
