TEHRAN, Iran (AP) — In a massive outpouring reminiscent of the Islamic Revolution three decades ago, hundreds of thousands of Iranians streamed through the capital Monday, and the fist-waving protesters denounced President Mahmoud Ahmadinejad’s claim to victory in a disputed election. Standing on a roof, gunmen opened fire on a group of protesters who had tried to storm a pro-government militia’s compound. One man was killed and several others were wounded in the worst violence since the disputed election Friday. Angry men showed their bloody palms after cradling the dead and wounded who had been part of a crowd that stretched more than five miles (nearly 10 kilometers) supporting reform leader Mir Hossein Mousavi. The huge rally — and smaller protests around the country — reinforced what has become increasingly clear since the election: the opposition forces rallying behind Mousavi show no signs of backing down. Their resolve appears to have pushed Iran’s Islamic establishment into attempts to cool the tensions after days of unrest. In his first public comment on the Iranian election, President Barack Obama said he was “deeply troubled by the violence I’ve been seeing on TV.” Although he said he had no way of knowing whether the election was valid, Obama praised protesters and Iranian youth who questioned the results. “The world is watching and is inspired by their participation, regardless of what the ultimate outcome of the election was,” he said. Police and other security forces stood by quietly — some sitting on stoops with their batons and shields resting behind them as the marchers swallowed the streets in parts of Tehran. Estimates put the turnout at hundreds of thousands overflowing the square, where crowds of 200,000 have filled the plaza in the past. Mousavi made his first public appearance since the polls closed, and he launched his claims that the vote was rigged to re-elect the hard-line president. Brief clips of the march were shown on state television in an extremely rare nod to anti-government protests.—-Contact The Daily Reveille’s news staff at [email protected]
