Hundreds of students at two Iranian universities have mounted protests in recent days to decry the expulsion of student activists and call for the resignation of a government-appointed campus president. Between 100 and 200 students at Allameh Tabatabai University in Tehran protested Tuesday against the recent banning of 40 students who had organized demonstrations against university authorities. In the central Iranian city of Shiraz, students have called for a university president to step down and demanded higher-quality food and housing. "The students are against the banning of their friends," said Rashid, a 25-year-old graduate student in Tehran who refused to give his family name out of fear he would be arrested. He said he was recently expelled from Allameh Tabatabai and later beaten by security guards when he tried to visit the university.
