A demonstrator spray-paints a slogan in Farsi on the Freedom Tower, as hundreds of thousands of supporters of leading opposition presidential candidate Mir Hossein Mousavi, who claims there was voting fraud in Friday’s election, turn out to protest the result of the election at a mass rally in Azadi (Freedom) square in Tehran, Iran, Monday, June 15, 2009. Writing in Farsi reads "Only Mousavi, Oh Hussein (referring to the 3rd Shiite Imam), Mir Hossein (referring to opposition candidate Mir Hossein Mousavi), and Only Mousavi". (AP Photo/Ben Curtis)
