Zürcher Nachrichten - Iran tensions rise in protests ahead of Mahsa Amini ceremony

"A student may die but will not accept humiliation," they chanted at Shahid Chamran University of Ahvaz, in the southwestern province of Khuzestan, in an online video verified by AFP.

Young women and schoolgirls have been at the forefront of protests sparked by Amini's death last month, after her arrest for an alleged breach of the Islamic republic's strict dress code for women.

The 22-year-old Iranian of Kurdish origin died three days after being taken into custody by the notorious morality police on September 13 while visiting Tehran with her younger brother.

Activists said the security services had warned Amini's family against holding a ceremony and not to ask people to visit her grave Wednesday in Kurdistan province, otherwise "they should worry for their son's life".

Wednesday marks 40 days since Amini's death and the end of the traditional mourning period in Iran.

State news agency IRNA published a statement it said was from the family, saying that "considering the circumstances and in order to avoid any unfortunate problem, we will not hold a ceremony marking the 40th day".

Activists said the statement was made under pressure and that tributes were nonetheless expected at Amini's grave.

- 'Attacked, strip-searched, beaten' -

Online videos showed students protesting Tuesday at Beheshti University and the Khaje Nasir Toosi University of Technology, both in Tehran, as well as Shahid Chamran University of Ahvaz.

The fresh demonstrations came after activists accused security forces of beating schoolgirls at the Shahid Sadr girls vocational school in Tehran on Monday.

"Students of the Sadr high school in Tehran have been attacked, strip-searched and beaten up," said the 1500tasvir social media channel.

At least one student, 16-year-old Sana Soleimani, was hospitalised, said 1500tasvir, which chronicles rights violations by Iran's security forces.

"Parents later protested in front of the school. Security forces attacked the neighbourhood and shot at people's houses," it added.

The education ministry said a dispute erupted between schoolgirls and their parents and school staff after the principal demanded they comply with rules over the use of mobile phones.

"The death of a student in this confrontation is strongly denied," a ministry spokesman said, quoted by Iran's ISNA news agency.

Families were seen clamouring for information outside the school in Tehran's Salsabil neighbourhood, in an online video verified by AFP.

And in western Kurdistan province, videos posted online by independent rights group Hengaw showed authorities on Tuesday evening patrolling roads leading into Saqqez, Amini's hometown.

The group, which monitors rights violations in Kurdistan, also tweeted that Iranian football stars Ali Daei and Hamed Lak were in Saqqez as they "want to take part in the 40th day funeral" and were staying at the Kurd Hotel.

But they "had been taken to the government guesthouse... under guard by the security forces", Hengaw said.

Daei has previously run into trouble with authorities over his online support for the Amini protests.

Unverified footage posted by Oslo-based Iran Human Rights group showed people gathering outside the Kurd Hotel in Saqqez "in their night protests".

- Top official heckled -

Such reports have fuelled further anger over the crackdown that Iran Human Rights said, in an updated toll Tuesday, had cost the lives of at least 141 protesters.

Deadly unrest has hit not only Kurdistan -- but also the city of Zahedan in the far southeast. IHR said 93 people were killed in demonstrations that erupted on September 30 over the reported rape of a teenage girl by a police commander.

Iran's Tasnim news agency said unidentified gunmen killed two Revolutionary Guards in Zahedan Tuesday, taking to eight the number of security personnel killed in Sistan-Baluchistan.

Despite what rights group Amnesty International has called an "unrelenting brutal crackdown", young women and men were again seen protesting in online videos on Tuesday.

"Death to the dictator" and "Death to the Revolutionary Guards", women chanted in Tehran metro stations, in videos shared on Twitter.

Students heckled the spokesman for ultraconservative President Ebrahim Raisi as he addressed Tehran's Khaje Nasir University, in a video published by the reformist paper Hammihan.

"Spokesman, get lost!" and "We don't want a corrupt system, we don't want a murderer", they shouted at Ali Bahadori Jahromi.

Teachers observed a strike around the country Sunday and Monday over the crackdown, and another work stoppage was said to be under way in Kurdistan on Tuesday.

Amnesty says the crackdown has cost the lives of at least 23 children, while IHR said Tuesday at least 29 children have been killed.

There has also been a campaign of mass arrests of protesters and their supporters, including academics, journalists and even pop stars.

State media said Tuesday that more than 210 people were charged in connection with the protests in Kurdistan, Qazvin and Isfahan.

IRNA said 105 people were charged over protests in Khuzestan, citing the local judicial authorities.
