Iranian state radio says the deputy chief of the UN nuclear watchdog will visit Iran within 10 days to discuss the country's disputed nuclear program. It would be the third visit to Iran by Olli Heinonen, deputy director general for the International Atomic Energy Agency. He has traveled to the capital Teheran twice in the past two weeks. Thursday's report quotes Iran's envoy to the IAEA, Ali Asghar Solanieh, as saying the visit and talks would take place within 10 days. It did not give further details. Last week, the IAEA announced a "milestone" agreement with Iran that aims to provide answers about allegations Teheran has tried to develop nuclear weapons under the cover of a peaceful atomic program.
