United Nations: The remarks by one of the Delhi gangrape convict blaming the victim for the assault are "unspeakable", UN Secretary-General Ban Ki-moon's spokesperson has said, stressing the need for men to get involved in halting violence against women.

Ban's spokesperson Stephane Dujarric refused to further comment on the remarks made by Mukesh Singh, the driver of the bus in which the 23-year-old paramedical student was brutally gangraped by six men on December 16, 2012.
