The head of the UN nuclear agency, the IAEA, has proposed sending a high-level mission to Iran, to address new fears about a possible military dimension to the country's nuclear programme. IAEA Director-General Yukiya Amano said there was credible information Iran had carried out activities relevant to the development of a bomb. He said there might be undeclared nuclear material and activities. Tehran says its programme is for peaceful purposes. The International Atomic Energy Agency's governing board has been debating the latest report on Iran released last week in the Austrian capital, Vienna, where it is based. "Our technical experts have spent years painstakingly and objectively analysing a huge quantity of information from a wide variety of independent sources, including from a number of member states, from the agency's own efforts and from information provided by Iran itself. The agency finds the information to be, overall, credible," Mr Amano said in a statement.
