Høyreorienterte studenter har pågrepet to redaktører for en studentavis på et av Teherans mest prestisjefylte universiteter. Moderate studenter forsøkte å beskytte dem.
De høyreorienterte anklaget redaktørene for å ha trykket islam-fiendtlige artikler. Men studentene sa artiklene er provokasjoner.
Scuffles broke out last week between reformist and right-wing students at Amirkabir University, after several works were accused of insulting Islam.
However, the editors say the offending articles were forged.
Right-wing students have called for a purge of liberal and Western influence from higher education establishments.
Reports say groups of reformist students were guarding the editors of the student publications in their dormitories to protect them from arrest.
One had already been arrested but three remained free. When the students tried to move the three editors to Amirkabir University they were stopped by unknown people and the editor of a publication called Atiye was taken away.
At BBC bruker uttrykket «høyreorientert» om de regimetro studentene er i seg selv interessant.
Det har vært lignende episoder på et annet universitet. De fanatiske studentene ønsker åpenbart påskudd til å drive utrenskninger og kampanjer.
And the right-wing students who were camped outside the gate have left because a committee is now negotiating with the ministry of education.
There has also been trouble in Tehran University after a fine art student drew angels without any hair, and then her lecturer made fun of her and asked if she too was bald under her headscarf.
Female students belonging to a right-wing group are planning a protest inside the university mosque on Monday.
