The UN\'s nuclear watchdog starts a two-day meeting in Vienna to discuss concerns over Iran\'s nuclear program. The IAEA chief Yu-kiya Amano says he proposes sending a special mission to Iran to address the issue. Amano says Iran has to answer questions over the possible militarization of their nuclear activities. The meeting follows an IAEA report that says Iran appears to have worked on a nuclear weapon design and may still continue secret research. The IAEA report set out a mass of intelligence suggesting Iran was seeking to build a nuclear bomb.
