A group of students began chanting anti-presidential slogans and smashed Iranian state television cameras installed to cover the event at Amir Kabir University. Other students, however, shouted out support for Ahmadinejad, Fars said.
Hundreds of students joined a rally at Amir Kabir University of Technology, a leading Iranian research institute, Sunday to protest against a clampdown on members of the reformist Muslim Student Association.
An earlier student rally in the Islamic Republic's capital Wednesday was held to draw attention to government tyranny.
