Speaking in a nationally televised speech, Iranian President Mahmoud Ahmadinejad called on the West "not to cause an everlasting hatred in the hearts of Iranians" by trying to force Iran to abandon uranium enrichment. The UN Security Council has demanded that Iran stop all uranium enrichment activity by April 28. Iran has rejected the demand, saying it has a right to develop the process. The head of the UN nuclear watchdog agency, Mohamed ElBaradei, is due in Iran this week for talks to try to resolve the standoff. "At this historic moment, with the blessings of God Almighty and the efforts made by our scientists, I declare here that the laboratory-scale nuclear fuel cycle has been completed and young scientists produced enriched uranium needed to the degree for nuclear power plants Sunday," Ahmadinejad said.
