Another major clash in Iran....

This was in North Tehran...

Witnesses in Iran say police have clashed with up to 3,000 protesters near a mosque in north Tehran.

They say security forces fired tear gas to disperse the crowd, and some demonstrators fought back, chanting: "Where is my vote?"

Witnesses at the scene tell The Associated Press that some protesters claimed they suffered broken arms or legs in Sunday's clashes around the Ghoba Mosque.

They say some young demonstrators screamed at police and then attacked them after the officers allegedly beat an elderly woman.
