Fresh protests broke out Monday in Iran over the death of a young woman who had been arrested by the "morality police" that enforces a strict dress code, local media reported.

Public anger has grown since authorities on Friday announced the death of Mahsa Amini, 22, in a hospital after three days in a coma, following her arrest by Tehran's morality police during a visit to the capital on September 13.

Demonstrations were held in Tehran, including in several universities, and the second city Mashhad, according to the Fars and Tasnim news agencies.

Protesters marched down Hijab Street in central Tehran denouncing the morality police, the ISNA news agency reported.

"Several hundred people chanted slogans against the authorities, some of them took off their hijab," Fars said, adding that "police arrested several people and dispersed the crowd using batons and tear gas".

On Sunday, police made arrests and fired tear gas in the dead woman's home province of Kurdistan, where some 500 people had protested, some smashing car windows and torching rubbish bins, reports said.
