The country’s morality police had announced stricter checks some weeks ago, the UN High Commissioner for Human Rights Volker Türk said.
Numerous women and girls have been detained in Iran for failing to heed head-covering regulations, and hundreds of businesses have been closed for failing to enforce them.
UN rights officials reported in Geneva on Friday.
The country’s morality police had announced stricter checks some weeks ago, the UN High Commissioner for Human Rights Volker Türk said.
The move appears to be a crackdown after women increasingly began to ignore the rules following a protest wave in the autumn of 2022.
Mr Türk expressed criticism of a draft law that will impose jail sentences of 10 years as well as flogging as punishment for failing to heed the rules on covering the hair.
He called on Tehran to remove sex-based discrimination and violence.
Türk also criticised the imposition of the death sentence on 33-year-old rapper Toomaj Salehi, whose songs attacked political abuse in the country and who was a prominent voice during the 2022 demonstrations.
According to Mr Türk’s office, nine men had been executed for their role in the protests that followed the death of Mahsa Amini in detention, who the morality police had detained for failing to wear her head covering properly.
