Iranian President Mahmoud Ahmadinejad delivers the weekly Friday prayer sermon at Tehran University during a parade marking Al-Quds (Jerusalem) Day in Tehran on September 18, 2009. Tens of thousands of Iranians chanted 'Death to the dictator', defying a heavy security presence to mount the first protest against Amadinejad's hotly disputed June re-election in two months, as the hardline president gave a keynote address to Jerusalem Day, an annual mass rally of solidarity with the Palestinians.
