US Secretary of State Condoleezza Rice said that Washington was concerned over Iranian threats to share the nuclear technology it is developing with other countries. We "have to be concerned when there are statements from Iran that Iran would not only have this technology, but would share it, share technology and expertise," Rice said at a news conference Tuesday in Turkey. Earlier, Iran's top leader, Ayatollah Ali Khamenei, said as he met with Sudanese President Omar al-Bashir that "Iran's nuclear capability is one example of various scientific capabilities in the country. ... The Islamic Republic of Iran is prepared to transfer the experience, knowledge and technology of its scientists."
