India's Supreme Court has upheld the death sentence of the sole surviving gunman of the 2008 attacks on Mumbai.
Mohammad Ajmal Amir Qasab, 24, had appealed against the lower court's order saying he had been denied a fair trial and that the prosecution had failed to prove its case.
Qasab was convicted of murder and other crimes in May 2010 and his first appeal was rejected in February 2011.
The Mumbai attacks claimed 165 lives. Nine gunmen were also killed.
The trial court found Qasab guilty in Mumbai on 3 May 2010 of murder, terrorist acts and waging war on India and sentenced him to death.
Qasab can now make a plea for clemency to the president.
The 60-hour siege of Mumbai began on 26 November 2008, targeting luxury hotels, the main railway station and a Jewish cultural centre.
Qasab and an accomplice carried out the assault on the station, killing 52 people.
India blamed Pakistan-based militant group Lashkar-e-Taiba for the attacks.
After initial denials, Pakistan acknowledged that the assault had been partially planned on its territory and that Qasab was a Pakistani citizen.
