TEHRAN, Iran - Iran's Intelligence Ministry says it has arrested at least 30 people allegedly linked to a spy network run by the CIA.

In a statement read on state TV Saturday, Iran's secret service says its agents uncovered activities of a CIA-run espionage network that sought to recruit Iranian spies through U.S. diplomatic missions that include the United Arab Emirates, Malaysia and Turkey.

The report didn't provide further details, but claimed the recruits had been asked to spy on Iran's research institutes, universities, nuclear programs and other sites.

Iranian authorities occasionally announce the arrest of people with alleged ties to foreign intelligence agencies, particularly the U.S., Britain and Israel.
