Indian prime minister Manmohan Singh has said he is "very saddened" by the death of a female student who was gang-raped in Delhi.
He has pledged to channel "emotions and energies into a constructive course of action."
The gang rape of a young woman in Delhi has exposed deep fissures in Indian society, as assault victims finally find their voices.
Speaking hours before his daughters attackers appeared in court, the father of the India rape victim has called for the harshest penalty.
After almost three weeks of protests over the rape of an Indian woman on a Delhi bus, the nation could face a national strike.
