Iran's feared Revolutionary Guards warned of a decisive confrontation if protestors came out today. More than 1,000 people defied them before security forces delivered on their threat.
"Police were beating protestors with batons and shooting into the air to scare them off," one Iranian dissident said by telephone.
On his Web site, opposition leader Mir Hossein Mousavi urged the protestors on. But he hasn't been seen in public for days, leaving opposition supporters disorganized.
