Iran's top prosecutor warns that authorities will take tough action against opposition protesters, a day after thousands took to the streets in anti-government demonstrations.
Iranian state media quote prosecutor Gholam Hossein Mohseni Ejeie as saying Tuesday that there will no longer be any tolerance for people working against national security.
Iranian security forces used tear gas and clubs against thousands of demonstrators in Tehran Monday. Authorities say 204 people were arrested.
Meanwhile, the state-run news agency IRNA reports minor clashes broke out at Tehran University Tuesday between pro-opposition students and government supporters.
Also Tuesday, the Web site of opposition leader Mir Hossein Mousavi reports a group of about 30 masked men on motorcycles harassed Mr. Mousavi outside his office.
The report says Mr. Mousavi told the men that if they were there to kill him, they should go ahead and do their job. The men left a short time after.
The United Nations High Commissioner for Human Rights, Navi Pillay, has called on Iran to respect the opposition's right to protest.
Speaking to reporters in Geneva Tuesday, Pillay said her agency wrote a letter to authorities in Tehran expressing its concerns.
She also said she is examining the fairness of trials against leading activists arrested during street protests that broke out in June following the disputed re-election of President Mahmoud Ahmadinejad.
Five people charged for their roles in the protests have been sentenced to death, and more than 80 have been given prison sentences of up to 15 years.
