Iran riot

Protestors start fires in a main street in Tehran, Iran, in the early hours of Monday. Iran’s supreme leader ordered Monday an investigation into allegations of election fraud, marking a stunning turnaround by the country’s most powerful figure and offering hope to opposition forces that have waged street clashes to protest the re-election of President Mahmoud Ahmadinejad. The results touched off three days of clashes, the worst unrest in Tehran in a decade. AP
