The Tehran Municipality has constructed locked barriers between the women's and men's subway cars in Tehran as gender apartheid deepens in Iran. Local media reported on Thursday that the actions are on the orders of conservative mayor Alireza Zakani, pointing out the safety risks of the measures which could prevent women escaping in the case of fire or emergencies. In May, a video circulated on social media showing the installation of a curtain to segregate the women's and men's subway cars in Tehran, reinforced in June when the head of Tehran City Council, Mehdi Chamran, said gender segregation was necessary and affirmed the enforcement of compulsory hijab on the subway.
