For the past four weeks, Iran has been convulsed by daily protests following the death in police custody of a 22-year-old woman, Mahsa Amini, on 16 September. The authorities’ response has been beyond brutal. More than 185 people have been killed and more than 110 students have been taken into custody. Many universities are, in effect, closed. Sharif University of Technology in Tehran, Iran’s leading centre for science and technology, has seen some of the worst crackdowns.
