Official: Iran won't stop uranium enrichment TEHRAN, Iran (AP) — An Iranian diplomat says Tehran will not stop uranium enrichment "for a moment," defying demands from the U.N. and world powers to halt its suspect nuclear program. The comments by Ali Asghar Soltanieh, Iran's delegate to the International Atomic Energy Agency, come just two days after senior IAEA investigators ended two days of intensive talks with Iranian officials on allegations the Islamic Republic may have carried out tests on triggers for atomic weapons.
