Al Arabiya TV aired a documentary entitled “The secrets of Iran’s nuclear program” and discussed the role of the Iranian Resistance in revealing these secrets.
In the summer of 2002, the West obtained a report disclosed and published by the People’s Mojahedin Organization of Iran (PMOI), and based on their information Iran had built a number of secret nuclear sites.

David Albright, a former International Atomic Energy Agency inspector, referred to a blow delivered by the Iranian opposition to the Iranian regime by exposing this information.
In 2001 we had tried but failed to obtain information on Iran’s secret nuclear site through various governments. However, all of a sudden in August 2002 the PMOI gave reports on two sites, one near Natanz and the other in Arak, he said.
At the time the PMOI held a press conference in Washington. Simultaneously, satellites began taking footages of the Natanz site located 300 kilometers south of Tehran, and they found a uranium enrichment site.

Ollie Heinonen, IAEA executive deputy from 2005 to 2010 says we obtained the first traces of the Natanz sites from the satellites. It was a very large complex. We were certain that this site had not appeared out of the blue. In fact it had taken years to build. In our opinion there were nuclear activities in Iran, which we knew nothing about.
