Iranian students chanted anti-government slogans to protest a minister's visit to their university in Tehran Tuesday, a reformist website reported.

Mowjcamp.com said at least 1,000 people took part in the gathering at Tehran's Sharif University after they learnt of the visit of Science Minister Kamran Daneshjou, whose ministry is in charge of higher education.

Daneshjou ran the Interior Ministry's election headquarters during Iran's disputed presidential poll in June. He was appointed science minister earlier this month in hardline President Mahmoud Ahmadinejad's new government.

The election, which was followed by huge opposition protests, plunged Iran into its deepest internal crisis since the 1979 Islamic revolution. The moderate opposition says it was rigged to secure Ahmadinejad's re-election. Officials deny it.

Monday, another pro-reform website, Norooz, said about 1,000 students held a rally at Tehran University, showing support for opposition leader Mirhossein Mousavi. Mowjcamp.com is a pro-Mousavi website.

It was not immediately possible to independently confirm the reports of student protests, which came some 10 days after security forces clashed with Mousavi supporters during annual anti-Israel rallies in Tehran.

The September 18 clashes in Tehran were the latest sign of continuing discontent about the election.

Iran's Revolutionary Guards largely quelled the huge opposition protests that erupted in the days after the vote, but opposition supporters have continued to stage sporadic rallies.

Thousands of people, including senior reformist figures, were detained after the election. Most have since been freed, though more than 100 remain in jail accused of orchestrating post-election street unrest.

The opposition says more than 70 people died during the unrest, more than double the official estimate.
