The controversy over the wearing of hijab (headscarves) by students crossed the state borders of Karnataka and surfaced in BJP-ruled Madhya Pradesh and Puducherry on Tuesday. As the Karnataka High Court – in response to an appeal by five women students in favour of headscarves, appealed for peace -- a minister in Madhya Pradesh ruled in favour of "discipline" and an "uniform dress code". In Puducherry, the authorities have asked the head of a government school in Ariyankuppam to inquire into allegations of a teacher objecting to headscarves in class.
