Reporting from Beirut — Opposition websites reported clashes between demonstrators and security forces in central Tehran this morning as the peak of a 10-day religious holiday approached.
The reformist website Rahesabz, or Green Path, said police used batons and fired teargas canisters to disperse demonstrators approaching Tehran's Imam Hossein Square.
Passersby in motor vehicles leaned on their horns in support, said the website, which has previously proven accurate.
Some news websites said the clashes at Imam Hossein Square had died down by the early afternoon but others said they were escalating to other main squares of downtown Tehran.
Iran has been roiled by renewed outbreaks of political unrest in recent days, with public demonstrations breaking out across the country in protests stemming from the country's disputed June 12 reelection of President Mahmoud Ahmadinejad.
