An Associated Press photographer saw gunmen fire on protesters near Tehran's Azadi Square a short time ago and believes at least one person was killed, the wire service reports.
More than 100,000 people are said to have gathered there, to protest the results of Friday's election — which the government says was won handily by President Mahmoud Ahmadinejad.
Meanwhile, in Washington the State Department has upped the U.S. rhetoric about the situation in Iran. "We are deeply troubled by the reports of violence, arrests and possible voting irregularities," said department spokesman Ian Kelly.

As some attempted to storm the building, people inside could be seen firing directly at the demonstrators at the northern edge of the square, away from the heart of the demonstration.
