Indian police are calling for the lone surviving suspect from November's terrorist attack on Mumbai to be put to death.
Maharashtra state Home Minister Jayant Patil says the death sentence is justified because of the rare and heinous nature of the crime.
Pakistani national Mohammed Ajmal Kasab has been charged with "waging war" on India for the three-day assault that left more than 170 people dead.
India also accuses Kasab of links to the Pakistan-based militant group Lashkar-e-Taiba, inflaming tensions between India and Pakistan.
The Press Trust of India reports Indian Home Minister Palaniappan Chidambaram is accusing Islamabad of failing to pursue the investigation, and of hampering the efforts of U.S. investigators (from the U.S. Federal Bureau of Investigation).
Chidambaram and U.S. intelligence chief Leon Panetta discussed the Mumbai attacks earlier this week, when the director of the U.S. Central Intelligence Agency traveled to New Delhi.
