Iran Expands Nuclear Technology

Installed close to 700 centrifuges, according to UN agency

The U.N.'s atomic agency says Iran is moving ahead to update a program the West fears could be used to make nuclear weapons.

An International Atomic Energy Agency report says Tehran has installed close to 700 high-tech centrifuges in an upgrade of its uranium enrichment program since the start of the year.

That represents an increase of about 100 since mid-April, when diplomats told The Associated Press that Iran was rapidly installing the equipment.
