Iran, Tehran: Defeated reformist presidential candidate Mir Hossein Mousavi (C) raises his arms as he appears at an opposition demonstrate in Tehran on June 15, 2009, for the first time since an election that has divided the nation. Opposition supporters defied a ban to stage a mass rally in Tehran in protest at President Mahmoud Ahmadinejad's landslide election win, as Iran faced a growing international backlash over the validity of the election and the subsequent crackdown on opposition protests.
