The Kremlin said on Monday that reported attempts by the U.S. FBI and CIA to recruit embassy staff in Washington were unacceptable.
Russia's ambassador to Washington, Anatoly Antonov, told state media that embassy employees had been threatened with physical violence, and were frequently badgered in the vicinity of the Embassy to work for the Federal Bureau of Investigation or the Central Intelligence Agency.
"We do share the concerns of the head of our diplomatic mission in the United States about the really rather brazen behaviour of the American intelligence agencies in relation to our citizens and to the employees of our mission," Kremlin spokesman Dmitry Peskov said.
"We consider it unacceptable."
