Frightened of this act of protest, the clerical regime dispatched large numbers of the State Security Force members, the Guards Corps and Intelligence Ministry agents to disperse the crowd.
Chanting anti-government slogans, the people resisted against the State Security Force and the Guards Corps and clashed with them.
Using water cannons, batons and clubs, the suppressive forces attacked the crowd. In the course of the clashes, which were particularly intense around the city's Chaharbagh Street, hundreds of people were injured and hospitalized. More than 100 demonstrators were arrested by the Guards Corps and taken to unknown locations.
Some 36 hours after the incident, the situation was still tense in some districts of Isfahan and plain-clothed Intelligence Ministry agents were controlling these areas.
