VIENNA, Austria - The International Atomic Energy Agency says a black market nuclear network operating from Pakistan had substantial and up-to-date information on how to make an atomic bomb.
The United Nations nuclear watchdog says much of the sensitive information was passed on to customers in electronic form.
The use of email attachments or CD-ROMs to spread information about how to make nuclear weapons is alarming because it gives a potentially unlimited number of customers access to the material, whether they are governments or individuals.
The IAEA's information was contained in a restricted report on Libya and based on information collected since that country renounced its efforts to make nuclear weapons in 2003.
