Iranian protesters, one of them wearing a wolf's head representing Israel, hold up placards bearing pictures of supreme leader Ayatollah Ali Khamenei (R) and his predecessor, the Islamic republic's founder Ayatollah Ruhollah Khomeini (L), during a rally marking Quds (Jerusalem) Day in Tehran on September 18, 2009. Iran's hardline President Mahmoud Ahmadinejad gave a keynote address to the annual mass rally of solidarity with the Palestinians at Tehran university on Quds Day, which was Khomeini's brainchild. Ahmadinejad said the Holocaust was a 'myth' and Israel was on its way to collapse, reiterating comments that sparked outrage around the world.
