This should be getting more play:
Despite the heavy police presence, large groups of demonstrators managed to congregate in parts of the city, according to opposition Web sites.
The opposition Web site Rah-e-Sabz reported isolated clashes between protesters and security forces midday Sunday, including police firing warning shots in the air and beating protesters. The Web site — which has reported protests reliably in the past — also said three people were shot by security services’ gunfire at an altercation at a bridge near Enqelab Square. It cited an eyewitness to the clash.
The Associated Press, citing opposition Web sites and eyewitnesses, also said security forces had opened fire on protesters. It was impossible to verify the accounts. Iranian authorities have forbidden press coverage of unauthorized demonstrations.
Ashura, a 10-day commemoration of a revered Shiite martyr, ends Sunday. Opposition forces have called on supporters to pour into the streets to demonstrate against the regime of Iranian President Mahmoud Ahmadinejad, who won contested presidential elections in June.
