NEW DELHI (AP) - Doctors say a young Indian woman who was gang-raped and severely beaten on a bus in New Delhi has died at a Singapore hospital.

A statement by Singapore's Mount Elizabeth hospital where the 23-year-old victim was being treated said she "died peacefully" early Saturday.

The horrific ordeal of the woman galvanized Indians, who have held almost daily demonstrations to demand greater protection from sexual violence, from groping to rape, that impacts thousands of women every day, but which often goes unreported.

She and a male friend were traveling in a public bus on Dec. 16 evening when they were attacked by six men who raped her and beat them both. They also inserted the rod in her body, stripped both naked and threw them off the bus on a road.
