Iranian President Mahmoud Ahmadinejad (C), flanked by bodyguards, waves to supporters before addressing tens of thousands of Iranians gathered in Azadi (Freedom) Square in southwestern Tehran to mark the 31st anniversary of the Islamic revolution on February 11, 2010. Ahmadinejad said Iran has produced a "first stock" of 20 percent enriched uranium for its nuclear programme and is capable of enriching it to 80 percent but will not do so.
