Russia accused the United States Tuesday of making baseless Cold War-style charges, rejecting Washington's announcement it had cracked a Russian spy ring that had spent years recruiting sources and digging for secrets.
"Such actions are baseless and have improper aims," the Russian Foreign Ministry said after the arrest of 10 suspected spies in the United States in the biggest espionage scandal for years.
An 11th suspect was arrested in Cyprus Tuesday and released on bail, police on the Mediterranean island said.
