NEW DELHI (AP) — Indian police charged six men with murder on Saturday, adding to accusations that they beat and gang-raped a woman on a New Delhi bus nearly two weeks ago in a case that shocked the country. The murder charges were laid after the woman died earlier today in a Singapore hospital where she has been flown for treatment. New Delhi police spokesman Rajan Bhagat said the six face the death penalty if convicted, in case that has triggered protests across India for greater protection for women from sexual violence, and raised questions about lax attitudes by police toward sexual crimes. The tragedy has forced India to confront the reality that sexually assaulted women are often blamed for the crime, forcing them to keep quiet and discouraging them from reporting it to authorities for fear of exposing their families to ridicule. Police often refuse to accept complaints from those who are courageous enough to report the rapes, and the rare prosecutions that reach courts drag on for years. Indian Prime Minister Manmohan Singh said he was aware of the emotions the attack has stirred, adding it was up to all Indians to ensure that the young woman's death will not have been in vain. The victim "passed away peacefully" early today at Mount Elizabeth hospital in Singapore with her family and officials of the Indian Embassy by her side, Dr Kevin Loh, the chief executive of the hospital, said in a statement.
