VIENNA (AP) - Diplomats say Iran plans to vastly increase the speed of its uranium enrichment program, which can make both reactor fuel and the core of nuclear warheads.
    
The diplomats say Iran has told the International Atomic Energy Agency that it wants to install thousands of high-technology machines at its main enriching site in central Iran.
    
Iran denies any interest in nuclear weapons. It says it's enriching only to power reactors and for scientific and medical purposes.
