Friday’s election in Iran was felt on the streets of San Francisco as hundreds rallied Saturday to dispute the official results declaring Mahmoud Ahmadinejad the winner of that country's presidential race.

Earlier in the day, thousands of protesters in Iran’s capitol city of Tehran took their anger to the streets. Police in riot gear used batons and shields to quell the largest street demonstrations Iran has seen in more than a decade. There are witness reports that police shot and killed at least one protester in Vanak Square.

Meanwhile, a smaller protest sprouted at San Francisco's U.N. Plaza.

Iranian-Americans at Saturday's rally said the results were a sham, a fiction created by Iran's president and supreme leader.

“Ali Khamenei is the head of corruption,” said protester Reza Mohajerinejad. “You know, he was the person who elected Ahmadinijad four years ago. They cheated also four years ago. But this time was totally different, because four years ago lots of people didn't vote. This time they wanted [their] vote,” he said.

Many of those who turned out Saturday were the same Iranian-Americans who voted in Emeryville Friday. Some said they had been turned away, told that the Iranian officials had run out of ballots.

They alleged that there was no way their votes were counted, and cited that as part of the proof that the election was rigged.

On Saturday, Iran's Interior Ministry reported opposition candidate Mir Hussein Moussavi won just 34 percent of the vote.

Moussavi-- who had promised to overturn many of the hardline reforms of Ahmadinijad-- has said the election was rigged.

But Saturday afternoon Iran’s Supreme Leader Ayatolla Ali Khamenei congratulated Ahmadinijad, closing the door on any appeals.

The Obama administration is saying it will continue to try to engage Iran's leadership in diplomacy, even with the questions circulating about the legitimacy of the election.

Ahmadinijad's re-election complicates the administration's plans to curb Iran's nuclear program and further complicates the peace process in the Middle East.

The White House had been hoping opposition candidate Moussavi would bring a new era of communication with the West.

Meanwhile, there are hopes the vocal opposition party and huge voter turnout could make President Ahmadinijad more receptive of diplomacy from the U.S.
