Paris - (AFP) - At least 100 Iranians arrested during more than 100 days of protests in their country face charges that carry the death penalty, the Oslo-based non-governmental organization Human Rights in Iran said Tuesday.

Iran is rocked by protests that erupted after the death on September 16 of Mahsa Amini, a 22-year-old Iranian Kurdish woman, who was arrested by the morality police for violating the Islamic Republic's dress code.

Tehran this month executed two youths linked to the protests, in an escalating crackdown by the authorities that activists say is aimed at spreading fear among the population.

In a report published on Tuesday, the organization revealed that 100 prisoners are at risk of the death penalty, including 13 who have been sentenced to death. He noted that many of them do not have access to a lawyer.

"By issuing death sentences and executing some of them against demonstrators, (the authorities) want people to get out of the street," said Mahmoud Amiri Moqaddam, head of the organization.

"This had a certain effect, but what we noticed in general was an increase in resentment against the authorities," he told AFP, adding that "their strategy of spreading fear with executions failed."

In an updated toll published on Tuesday, the organization said that 476 demonstrators had been killed since mid-September.

The United Nations said in November that at least 14,000 people had been arrested since the protests began in Iran.

On December 12, Majid Reza Rahnavard, 23, was hanged in a public place after a court in Mashhad (northeast) convicted him of killing two members of the security forces.

Four days earlier, Mohsen Shakari (23 years old) was executed for injuring a security officer.

The judiciary announced that nine other people had been sentenced to death in connection with the protests, and two of them were allowed to be retried.

The father of a death row convict, Mohamed Qabadlo, called on social networks for his son's release.

"Mohammed has no criminal record yet," the father said in a video clip published this week, stressing that he suffers from a mental disorder.

The 22-year-old was accused of "corruption on earth" after he "attacked two policemen with a car, killing one of them."

The judiciary's Mizan Online website reported that Qabadlo underwent a psychiatric evaluation, which concluded he "was aware of the nature of the crime he had committed".
