The FBI on Monday released a treasure trove of surveillance videos, documents and photos of its investigation into Russian spies in the United States.
The decade-long case, dubbed "Operation Ghost Stories," culminated in the arrests of 10 Russian spies last year, and "provided a chilling reminder that espionage on U.S. soil did not disappear when the Cold War ended," the FBI said on its website.
The material was released by the FBI after a Freedom of Information Act (FOIA) request.
"The highly publicized case also offered a rare glimpse into the sensitive world of counterintelligence and the FBI’s efforts to safeguard the nation from those who would steal our vital secrets," the FBI said.
