"The updated information presented by us indicates that the United States keeps deliberately applying an entire range of measures and restrictions to our Permanent Mission and its employees aimed at reducing the effectiveness of our interaction with the UN, but moreover, at the provision of psychological pressure on Russian diplomats," Zabolotskaya said.
“How else can you explain the ever-increasing intrusive recruiting tactics by local security services who approach employees on the street and at the airport,” she said.
Zabolotskaya said contextual advertising is used on social networks, search engines and on video hosting sites, for example YouTube, to promote solicitations to cooperate with the FBI.
The latest comes just over a month after the foremost US spy agency, the CIA, embarked on a social media crusade to target the Russian public to establish so-called "secure" lines where secrets could be '"shared" with American agents.
At the time, Kremlin Spokesman Dmitry Peskov told reporters that the targeting campaign was being monitored by officials.
