This would be done through the Johannesburg Holocaust and Genocide Centre.READ: Jewish Board to meet school after 'anti-Semitic' chants during school playComment from the said school was not immediately available.During the festival on May 18, pupils from the high school allegedly chanted "Heil Hitler" during a play called The Boy in the Striped Pyjamas, which King David Victory Park pupils were performing.At the time, Kahn said it was shocking that pupils could make such statements, despite there being Holocaust education in the curriculum."The majority of Jews in South Africa and around the world have in some way been touched by the Holocaust, through losing a family member or knowing someone who has lost a family member. This is something very worrying."Kahn said she did not think the school was promoting such behaviour."But we need to find ways of the school educating and discouraging all forms of hatred, be it racism, anti-Semitism, Islamophobia, homophobia and all forms of hatred, particularly in the schooling system."
