A group of Iranian students, incensed at rules imposed on June 12 requiring female students to wear a maqna’a – a conservative Islamic headscarf in black that covers the head, neck and shoulders – began a sit-in in protest. They also wrote an open letter to the university administration, which said: “We have nothing to say to you except ‘no’.” A number of students were beaten and arrested for taking part in the protest, while also being threatened with suspension and even death. Thousands of people have posted “no” on their social media accounts in solidarity and students at dozens of other universities have published open letters in support of the Tehran art students.
