Iranians at home and abroad marked the first anniversary on Saturday of the death in police custody of Mahsa Amini, with activists speaking of a renewed crackdown to prevent any resurgence of the protests which rocked major cities last year. Amini, a 22-year-old Iranian Kurd, died a few days after her arrest by religious police for allegedly violating the strict dress code for women in force since shortly after the 1979 revolution. Her family says she died from a blow to the head but this is disputed by Iranian authorities. Anger over her death rapidly expanded into weeks of taboo-breaking protests which saw women tearing off their mandatory headscarves in an open challenge to the Islamic Republic’s system of government under supreme leader Ayatollah Ali Khamenei. But after several months, they lost momentum in the face of a crackdown that saw security forces kill 551 protesters, according to Norway-based Iran Human Rights (IHR), and arrest more than 22,000, according to Amnesty International. Iranian authorities say dozens of security personnel were also killed in what they describe as “riots” incited by foreign governments and hostile media. Seven men have been executed after being convicted in protest-related cases. Campaigners say the authorities have renewed their crackdown in the runup to the anniversary, putting pressure on relatives of those killed in the protests in a bid to stop them speaking out. New York-based Human Rights Watch said family members of at least 36 people killed or executed in the crackdown had been interrogated, arrested, prosecuted or sentenced to prison over the past month. “Iranian authorities are trying to impose a chokehold on dissent to prevent public commemoration of Mahsa Jina Amini’s death in custody, which has become the symbol of the government’s systematic oppression of women, injustice and impunity,” said HRW’s senior Iran researcher, Tara Sepehri Far. The two journalists who did the most to publicise the Amini case – Niloufar Hamedi and Elahe Mohammadi who respectively reported from her hospital and funeral – have been held in prison for almost a year. Another reporter, Nazila Maroufian who interviewed Amini’s father Amjad, has been arrested repeatedly. Amjad Amini has told Persian media based outside Iran that he plans to hold a commemoration for his daughter in their hometown of Saqez in Kurdish-populated western Iran later Saturday. Outlets, including Prague-based Radio Farda, said he was summoned by intelligence officials after his announcement. He was not arrested but one of Amini’s uncles, Safa Aeli, was detained in Saqez on September 5. According to Kurdish-focused news outlet Hengaw, the government has sent additional security forces to Saqez and other towns in western Iran that could become flashpoints. On Saturday, Hengaw said, “repressive forces” were deployed around the Amini family residence in Saqez. It posted photos on X, formerly Twitter, showing armed men in fatigues on the streets of Saqez, as well as video of shops shuttered and on strike to mark the anniversary in Saqez, Sanandaj and other cities of Kurdistan province. Later, rights groups said Amjad was briefly detained by security forces on the first anniversary of his daughter’s death. Amjad Amini was warned against marking the anniversary of his daughter’s death before being released, the Kurdistan Human Rights Network said. Iran’s official IRNA news agency denied that Amjad Amini was arrested, but it did not say if he was briefly detained or warned. A massive security force presence was deployed in Iran’s mostly Kurdish areas on Saturday in anticipation of unrest, according to human rights groups. Widespread strikes were also reported in multiple cities in Iran’s Kurdistan region. However, IRNA said Amini’s hometown of Saqez was “completely quiet” and that calls for strike in Kurdish areas had failed due to “people’s vigilance and the presence of security and military forces”. It quoted an official in the Kurdistan province as saying: “A number of agents affiliated with counter-revolutionary groups who had planned to create chaos and prepare media fodder were arrested in the early hours of this morning.” While some women are still seen walking in public without headscarves, particularly in wealthy, traditionally liberal areas of north Tehran, the conservative-dominated parliament is currently considering a draft law that would impose far stiffer penalties for non-compliance.
