The ministry's Public Relations Office added in the statement that the US-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 US 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 US 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.
