Riot police in Tehran continue to lead a crackdown on demonstrators following a disputed presidential election.
Said White House press secretary Robert Gibbs of Obama: ``I think he has been moved what we've seen on television. I think particularly so by images of women in Iran who have stood up for their right to demonstrate, to speak out and to be heard.''
Gibbs said Monday that Obama continues to have ``concerns and questions'' about the way Iran's presidential election was conducted this month.
Obama has faced criticism from Republican lawmakers who say he has not spoken forcefully against Iran's leaders.
Iran's security forces are showing once again that they mean business.
Riot police Monday attacked hundreds of demonstrators with tear gas and fired live bullets in the air, to break up a rally in central Tehran.
Witnesses say helicopters hovered overhead as about 200 protesters gathered. But they say the anti-riot police quickly put an end to the demonstration.
Earlier in the day, the Revolutionary Guard ordered demonstrators to ``end the sabotage and rioting activities'' and called their resistance a ``conspiracy'' against Iran.
Meanwhile, the country's highest electoral authority is acknowledging that there were voting irregularities in 50 districts. It's the most serious official admission of problems with the vote so far. But the Guardian Council insists the problems did not affect the outcome of the vote.
