Iranian students staged a new demonstration at Tehran University on Sunday, damaging the main gate to allow outsiders into the campus and denouncing President Mahmoud Ahmadinejad.

The protesters chanted slogans against the president and carried banners calling for the release of three fellow students who have been held since May in a high-profile case, the Fars news agency and state-run IRNA reported.

The students also burned a copy of Kayhan newspaper, the mouthpiece of the clerical establishment that is critical of the Iranian reformist movement.
