(CNSNews.com) - The Russian intelligence service has arrested an American diplomat on suspicion of spying, according to reports from Moscow Tuesday.
The diplomat, an unnamed woman, is reportedly a second secretary in the military-political department of the U.S. Embassy.
Alexander Stanovic, a spokesman for the FSB counter-intelligence agency, said she was arrested while on a "spying mission" and that she was trying to obtain secret documents from a Russian citizen.
The diplomat apparently has been handed over to embassy officials, and no further information was immediately available.
Early Tuesday, Russian news organizations carried reports from Washington quoting U.S. military officials as saying a Navy code-breaker was being held on charges of passing secrets to Russia in 1994.
The reports said Petty Officer (First Class) Daniel King, 40, was awaiting a hearing on charges of espionage and disclosing classified information to a colleague.
Naval officials were quoted as saying the incident was thought to have been an isolated event, rather than an indication of a major security breach.
At the time of the alleged incident, King was based at a Navy espionage decoding unit at the National Security Agency.
