Russia's foreign ministry on Friday accused the US authorities of directly violating its diplomats' immunity with a planned FBI search of the San Francisco consulate including diplomats' accommodation.

"The demands of the US authorities create a direct threat to the security of Russian citizens," foreign ministry spokeswoman Maria Zakharova said in a statement. 

"American special services intend on September 2 to carry out a search of the consulate in San Francisco including of employees' apartments." She specified that the search would be carried out by FBI agents
