More than 3,000 protesters chanted, "death to despotism" and "free all political prisoners."
Shortly after the protest began, members of the Bassij and Revolutionary Guards, posing as the Students' Bassij, attacked the crowd with clubs and knuckle-dusters. Clashes continued from 1:00 to 3:00 p.m. and a number of students were arrested.
