Indian authorities have charged six men with murder, following the death of an student who was brutally gang-raped earlier this month on a bus in New Delhi.

Police say the six men could face the death penalty if convicted.

The 23-year-old woman died early Saturday of severe organ failure at a hospital in Singapore. She underwent multiple surgeries in New Delhi before being flown to Singapore Thursday for special treatment.

News of her death prompted thousands of people to stage peaceful protests in the capital, despite tight security to prevent mass demonstrations. The protesters demanded justice for the victim and safety for women.

New Delhi has been rocked by mass protests since the women was attacked on December 16th.

Demonstrators also mourned her death with protests Saturday in Mumbai and Bangalore.

Indian Prime Minister Manmohan Singh said he is “deeply saddened” by the woman's death. He said the emotions the case has generated are “perfectly understandable.”

The woman's body was set to be flown back to India Saturday.

The woman is reported to have been traveling with a male companion on a charter bus in New Delhi on December 16 when six men on board beat them both with an iron rod. The woman was raped repeatedly. Reports say a rod was used in the rape, causing some of her internal injuries. She also suffered brain injuries. The woman and her friend were thrown from the moving bus.

The male friend survived the attack. Neither the woman nor her friend have been identified.

Many rapes in India go unreported. India's government has been criticized for being slow to understand the outrage that followed the incident, in a country where crimes against women are growing, and where police figures show that rape is among the fastest growing crimes.
