Also on Saturday, authorities reported that the gunman who killed 15 people at a major Shia holy site in southern Iran earlier this week died in a hospital from injuries sustained during his arrest. Tehran has not disclosed details about the man who carried out Wednesday's attack on Shah Cheragh in Shiraz, Iran's second-holiest Shiite shrine.
The militant Islamic State group claimed responsibility for the shooting. But Iran's government has tried to blame the attack on the largely peaceful protests roiling the country, without offering evidence. Amaq, the militant group's media arm, released a video on Saturday that purportedly shows the Shiraz attacker pledging allegiance to the group.
The nationwide unrest _ sparked by the Sept. 16 death of Mahsa Amini in the custody of the country's morality police, has rocked the Islamic Republic for a month and a half. Amini died after being detained for allegedly violating the country's strict Islamic dress code for women.
At the funeral for victims of the shooting attack in Shiraz, the chief of the Revolutionary Guard, Gen. Hossein Salami, appealed to Iranians to stop protesting. The Guard and other security forces have violently cracked down on demonstrations with live ammunition, anti-riot pellets and tear gas.
``Today is the end of the riots. Do not go to the streets anymore!'' Salami said on Saturday as crowds thronged the coffins of the victims of the Shiraz attack. ``We are telling our youth, the minority of you who have been deceived, stop the evil acts.''
He added in the same harsh tone: ``This ominous sedition will bring no happy ending to you. Do not ruin your future!''
Despite the threat, student associations reported protests at dozens of universities across the country on Saturday, from the capital of Tehran to the central cities of Isfahan and Yazd. Videos spread online show students chanting for freedom and the end of Iran's clerical rule.
At the Kurdistan University of Medical Sciences in the northwestern city of Sanandaj, the human rights group Hengaw reported that security forces opened fire on protesters, critically wounding a student.
University campuses have become hotbeds of opposition, fueling the protest movement and prompting a harsh backlash from security forces.
The Iranian government has repeatedly alleged that foreign powers have orchestrated the protests, without providing evidence. The protests have become one of the most serious threats to Iran's ruling clerics since the 1979 Islamic Revolution.
The protests first focused on the state-mandated hijab, or headscarf, for women but quickly grew into calls for the downfall of Iran's theocracy itself. At least 270 people have been killed and 14,000 have been arrested in the protests that have swept over 125 Iranian cities, according to the group Human Rights Activists in Iran.
A court in Tehran on Saturday heard the case of several protesters charged with ``corruption on earth'', a term often used to describe attempts to overthrow the Iranian government that carries the death penalty. Judicial officials have announced charges against hundreds of people in Tehran and other provinces as they seek to quash dissent.
On Friday, Iranian security forces opened fire on demonstrators in the southeastern flash point city of Zahedan, killing at least two people, according to activists.
Zahedan, in Iran's long-restive Sistan and Baluchestan province, has seen the deadliest violence in protests so far. Activists estimate that in Zahedan alone, nearly 100 people have been killed since a Sept. 30 rally set off a violent police response.
