Key Points
- In a viral video, a man can be seen throwing yoghurt on two women whose hair is uncovered.
- Arrest warrants have reportedly been issued for the man and the two women.
- On Saturday, Iran's president reiterated the country's legal requirement for women to wear the hijab.
Iran's President Ebrahim Raisi said on Saturday that the hijab was the law in Iran, after a viral video showed a man throwing yoghurt at two unveiled women in a shop near a holy Shi'ite Muslim city.
Growing numbers of women have defied authorities by discarding their hijabs - or headscarf - in September.
The 22-year-old Kurdish woman died in the custody of the morality police for allegedly wearing her hijab "improperly".
Security forces violently put down the revolt.
Judicial authorities in a town near the northeastern city of Mashhad issued arrest warrants for the man seen pouring yoghurt over the heads of the two women — a mother and daughter.
The women were also the subject of arrest warrants for flouting Iran's strict female dress rules, state media reported.
Risking arrest for defying the obligatory dress code, women are still widely seen without hijabs in malls, restaurants, shops and streets around the country.
Videos of women resisting the morality police have flooded social media.
"If some people say they don't believe (in the hijab)... it's good to use persuasion," Mr Raisi said in live remarks on television.
"But the important point is that there is a legal requirement ... and the hijab is today a legal matter."
Authorities said the owner of the dairy shop, who confronted the attacker, had been warned.
Reports on social media showed the shop had been shut, and the owner was quoted by a local news agency as saying he had been allowed to reopen and was due to "give explanations" to a court.
Judiciary chief Gholamhossein Mohseni Ejei earlier threatened to prosecute "without mercy" women who appear in public unveiled, Iranian media reported.
"Unveiling is tantamount to enmity of (our) values," Mr Ejei was quoted as saying by several news sites.
Under Iran's Islamic sharia law, imposed after the 1979 revolution, women are obliged to cover their hair and wear long, loose-fitting clothes to disguise their figures.
Violators have faced public rebuke, fines or arrest.
Describing the hijab as "one of the civilizational foundations of the Iranian nation" and “one of the practical principles of the Islamic Republic,” an Interior Ministry statement on Thursday said there would be no “retreat or tolerance” on the issue.
It urged citizens to confront unveiled women.
Such directives have in past decades emboldened hardliners to attack women without impunity.
