A leading Iranian actress, Taraneh Alidoosti, who won an Oscar for her work in The Salesman, also carried a sign that said: “Woman, Life, Freedom” in Kurdish.
The catchphrase has evolved into a popular rallying cry for demonstrators.
Seven weeks have passed since Mahsa Amini died while being held by the police; prompting protests.
After being detained by Tehran’s morality police for reportedly breaking Iran’s severe laws mandating women to cover their hair with a hijab, or Islamic headscarf, the 22-year-old passed away.
One of Iran’s most popular actors, Ms. Alidoosti, has more than 8 million Instagram followers. She starred in The Salesman, which took home the Best International Feature Film Oscar in 2016.
Before pausing her work to assist the families of those murdered in the security forces’ crackdown on protesters, she had sworn to stay in Iran at all costs.
Local human rights groups estimate that 14,800 individuals have been imprisoned and at least 328 people have been killed.
The star’s post is the most recent show of solidarity from Iran’s top artists and athletes.
Sardar Azmoun, a prominent footballer from Iran, supported protesters last month as the government’s violence grew more severe. In an Instagram post, the Bayern Leverkusen forward criticised the security forces, writing: “Shame on you for easily killing the people and viva women of Iran. Long live Iranian women!”
