The footage from Tehran today looks like urban warfare. Gone are the massive crowds. Instead we see bands of civilians under attack from bands of thugs, gunshots, flames, thin crowds chased through side streets. If the authorities succeed in keeping demonstrators dispersed and on the run, they could swiftly seize the upper hand. The Web site Tehran Bureau is reporting forty dead and more than two hundred wounded. The victims are seeking aid in foreign embassies rather than hospitals, according to Twitter reports from Tehran.
