A female student gang-raped on a bus in India's capital Delhi has died at a Singapore hospital, doctors say.
"The patient passed away peacefully at 4:45am on 29 Dec 2012," a statement from the hospital said. The patient's family had been by her side, it added.
The 23-year-old had arrived in Singapore on Thursday after undergoing three operations in a Delhi hospital.
The attack earlier this month triggered violent public protests in India that left one police officer dead.
"The patient had remained in an extremely critical condition since admission to Mount Elizabeth Hospital," a statement from hospital chief executive Kelvin Loh said.
"She had suffered from severe organ failure following serious injuries to her body and brain. She was courageous in fighting for her life for so long against the odds but the trauma to her body was too severe for her to overcome," the statement went on.
"We are humbled by the privilege of being tasked to care for her in her final struggle," Mr Loh said.
A team of eight specialists had tried to keep the patient stable, but her condition continued to deteriorate over the two days she was at Mount Elizabeth Hospital, he added.
The victim and her friend had been to see a film when they boarded the bus in the Munirka area of Delhi, intending to travel to Dwarka in the south-west of the city.
Police said she was raped for nearly an hour, and both she and her companion were beaten with iron bars and thrown out of the moving bus and into the street.
