Iranian President Mahmoud Ahmadinejad said Friday that Iran was building a second uranium enrichment facility near the Shia Muslim city of Qom , about 100 miles southwest of Tehran .

Iran told the IAEA there is no nuclear material at the site , an agency spokesman said . Iran has denied its goal is to develop nuclear weapons , a concern of the United States and other Western nations . Esmail Kowsari , a senior Iranian lawmaker , said Iran 's need for nuclear fuel is outpacing the limited amount of uranium it can enrich at its only other plant in Natanz . But Iran 's activities , along with its anti-Western and anti-Israel rhetoric , have troubled international powers working to stop the development of an Iranian nuclear program . The country 's Islamic Revolutionary Guard Corps said it is planning to stage `` massive missile exercises '' or war games on Sunday to promote the armed forces ' `` deterrent power , '' the semi-official Fars News Agency reported . The tests are code named `` Payambar-e Azam 4 , or `` The Great Messenger , '' the corps said in its announcement . Iran 's announcement came ahead of a planned meeting October 1 between it and the five permanent United Nations Security Council members , plus Germany . Leaders from the United States , France and Britain made a joint announcement , accusing Iran of violating international agreements by keeping the construction plan a secret . `` This is a serious challenge to the global non-proliferation regime and continues a disturbing pattern of Iranian evasion , '' President Obama said Saturday in his weekly radio address . `` That is why international negotiations with Iran scheduled for October 1 now take on added urgency , '' he said . `` My offer of a serious , meaningful dialogue to resolve this issue remains open . But Iran must now cooperate fully with the International Atomic Energy Agency and take action to demonstrate its peaceful intentions . '' Ali Asghar Soltanieh , Iran 's ambassador to the IAEA , told Press TV Saturday that Iran is `` very disappointed with the hasty , unjustified hostile reaction yesterday by three leaders .
