From EADSURLS 14/2003: UNCLASSIFIED REPORT TO CONGRESS ON THE ACQUISITION OF TECHNOLOGY RELATING TO WEAPONS OF MASS DESTRUCTION AND ADVANCED CONVENTIONAL MUNITIONS, 1 JANUARY THROUGH 30 JUNE 2003.
United States Central Intelligence Agency (CIA). Web-posted November 10, 2003.
In its most recent semiannual unclassified report to Congress on the acquisition of technology relating to weapons of mass destruction, the CIA asserts that "Tehran has been pursuing a clandestine nuclear weapons program, in violation of its obligations as a party to the Nuclear Nonproliferation Treaty (NPT). To bolster its efforts to establish domestic nuclear fuel-cycle capabilities, Iran sought technology that can support fissile material production for a nuclear weapons program." This report also covers the attempts of other countries and of non-state organizations to procure WMD. There are also sections on key suppliers such as Russia, China and North Korea.
