Iran won't stop uranium enrichment program
None
Iran's nuclear chief Fereidoun Abbasi says his country won't stop uranium enrichment activities the U.N. has demanded it halt.
Iran says it needs the material for a medical research reactor, and that the level of enrichment nearly 20 percent is far below the more than 90 percent needed to build a nuclear weapon. But US officials have expressed concern Iran is taking steps toward greater enrichment. (AP)
