In the third episode in our series on Iran, Jo Glanville meets Professor Karima Bennoune, Lewis M. Simes Professor of Law at the University of Michigan and former UN rapporteur in the field of cultural rights. Professor Bennoune is leading a campaign for gender apartheid to be recognised as a crime against humanity. The term describes the institutionalised oppression of women based on gender. Professor Bennoune, alongside campaigners in Afghanistan and Iran, wants to change that, and is calling for gender apartheid to be included in a UN treaty to prevent and punish crimes against humanity.
