Four of the men held guilty of raping and torturing a 23-year-old medical student on a moving bus in Delhi in December 2012 will hang, the Supreme Court said today, describing the crime as a "story of a different world". "I am khush (happy)," said Nirbhaya's mother Asha Devi. Her father BN Singh, who says he will never stop missing his daughter, added, "It's not just a victory for my family, it's a victory for each and every woman in our country."
