The Iranian Intelligence Ministry announced Saturday that it has identified and dismantled a large spy network linked to the United States Central Intelligence Agency (CIA).

The elite and faithful forces of the Intelligence Ministry were able to arrest a number of 30 American-linked spies in their confrontation with the CIA agents and through numerous intelligence and counter-intelligence operations, the statement said.

Also, 42 CIA operatives linked to the network have been identified in various parts of the world, the ministry said in the statement.

It said that not only did the Intelligence Ministry defuse the CIA's heavy aggressive operations but the intelligence ministry's agents have succeeded in feeding false information to the CIA through a number of double-agents.

The ministry's Public Relations Office added in the statement that the U.S.-related spy network was operating under the cover of the so-called job-finding centers to attract Iranian citizens to cooperate with them, by promising them jobs and education opportunities, and deceiving them with visa and entry permission to the United States.

The network was "established by a number of the leading CIA operatives" in some countries, and due to the massive intelligence and counter-intelligence work, the Iranian intelligence agents succeeded in discovering and completely dismantling the network, said the statement.

"The network used a wide range of data bases and U.S. embassies and consulates in several countries, specially in the United Arab Emirates (UAE), Malaysia and Turkey, to collect information on Iran's scientific, research and academic institutions in the fields of nuclear energy, air and defense industries and biotechnology," the Iranian Intelligence Ministry said.

The statement further pointed out that the U.S. network also spied on Iran's oil and gas pipelines, power and telecommunication grids, airports, customs departments, network security and banks for future sabotage operations.

In the past years, Iranian authorities have been accusing the United States and Israeli intelligence services of spying on Iran's military and nuclear programs.

In January, Iran said it had dismantled an Israeli spying network and arrested a group of its terrorist- spies who were linked to the assassination of its nuclear scientist.

An Iran's Intelligence Ministry announcement said then that, "In order to carry out its non-human, anti-Islamic and anti-Iranian wills, the Mossad (Israeli intelligence agency) has used its bases in some European, non- European and some neighboring states of the Islamic Republic to conduct the terror attack against Dr. Massoud Ali-Mohammadi."

In January 2010, Massoud Ali-Mohammadi, the nuclear scientist from Tehran University, was killed by a remote-controlled bomb attached to a motorbike parked near his house.

In November 2010, another Iranian nuclear scientist Majid Shahriar was also killed by a bomb attached to his car on the way to his work.

Also, Iranian nuclear officials have accused the United States and Israel of cyber-attacks on Iran's Bushehr nuclear power plant computers but they have denied any serious damage to the facilities.
