Iran's parliament and the judiciary are reviewing a law which requires women to cover their heads, and which triggered more than two months of deadly protests, the attorney general said.
The demonstrations began after Mahsa Amini, a 22-year-old Iranian of Kurdish origin, died in custody on September 16 after her arrest by Iran's morality police for an alleged breach of the dress code.
Protesters have burned their head coverings and shouted anti-government slogans. Since Amini's death a growing number of women are not observing hijab, particularly in Tehran's fashionable north.
The hijab headscarf became obligatory for all women in Iran in April 1983, four years after the 1979 revolution that overthrew the US-backed monarchy.
