And from the White House....the silence is deafening.
Tens of thousands of Iranians took to the streets of Tehran Monday, defying a country-wide crackdown with protests against the hotly-disputed results of last week's presidential election.
Chanting crowds, some wearing green campaign colors, greeted Mir Hossein Mousavi, the defeated candidate in Friday's election, as he slowly moved through the streets on the back of a car.
Scuffles broke out as Ahmadinejad supporters, riding motorbikes and armed with sticks, attacked the demonstrators along the route.
But Iranian television painted a more violent picture, saying that pro-government militia opened fire on the crowd of Mousavi supporters, killing at least one, Reuters reported.
