Tehran protesters swarm Basij Militia man.

A large poster described as bearing images of ayatollahs Khomeini and Khamenei is at the center of the action. In the first video, a man dressed in a sweater identified as a member of the Basij militia attempts to gather up the poster off the street as the crowd of protesters in the vicinity chants, "Na Ghaza! Na Lobnan! Tunis o Misr o Iran!" (Not Gaza! Not Lebanon! Tunisia and Egypt and Iran!). Suddenly, a fight breaks out and the purported Basij member is swarmed. We cannot confirm the man's membership in the militia, but this description of the event has been independently supported by @madyar via Twitter.Source.
