Iran will not stop higher grade uranium enrichment

Iran will not stop higher grade enrichment of uranium due to external demands, Tehran's top nuclear official was quoted as saying on Tuesday.


Western powers want Iran to halt enrichment of uranium to a fissile concentration of 20 percent as it represents a significant step closer to the level that would be required to make nuclear bombs. Iran says it needs uranium refined to 20 percent for its medical research reactor in Tehran. (Reuters)
