The Web site of an Iranian opposition leader reported Friday that his car was shot at by pro-government demonstrators, shattering its windows.
The report by Sahamnews said the shooting happened while former presidential candidate Mahdi Karroubi was leaving a building in Qazvin, some 90 miles west of Teheran.
The report added that some 500 people had been demonstrating outside the building where he was staying since the day before.
The site described the demonstrators as armed and said police were unable to disperse them.
Karroubi ran in June's disputed elections that reformists say was won by the incumbent through fraud.
