Iranian state television says Iran has developed a new generation of centrifuges to enrich uranium. The report said the centrifuges have higher speed and will be unveiled later Wednesday. The West believes Iran is developing a nuclear weapons capability, and has imposed sanctions on Tehran to pressure it to stop enriching uranium. Iran says its nuclear ambitions are peaceful. A team from the United Nations nuclear agency is scheduled to make a two-day visit to Iran beginning Monday. The International Atomic Energy Agency's chief inspector said experts had "intensive discussions" with Iran about its nuclear aims during a trip in late January, and that both sides had "a lot of work to do." The IAEA issued a report in November citing evidence of Iranian efforts to design a nuclear weapon in violation of international sanctions and agreements. Iran says the report was based on fabrications. Some information for this report was provided by AFP and Reuters. Join the conversation on our social journalism site - [1]Middle East Voices.
