Iranian security forces cracked down on protests in Kurdish areas of the country on Saturday and briefly detained the father of Mahsa Amini, a year after the young woman's death in custody set off some of the worst political unrest in four decades.
The Revolutionary Guards detained a dual national suspected of "trying to organize unrest and sabotage", the official news agency IRNA reported, one of several arrests of "counter revolutionaries" and "terrorists" reported.
As night fell on Saturday, a heavy security force presence in Iran's mostly Kurdish areas appeared to have deterred large-scale protest rallies but human rights groups reported sporadic confrontations in several areas of the country.
The death of Mahsa Amini, a 22-year-old Kurdish woman arrested by the morality police last year for allegedly flouting mandatory dress codes, triggered months of some of the biggest protests against the Islamic Republic's Shi'ite clerical rule ever seen and drew international condemnation.
Despite the heavy security presence on Saturday, there were indications of protest actions at various points around the country. Videos posted on social media showed people gathered on a main avenue in the capital Tehran cheering a young protesting couple as drivers honked their car horns in support.
