NEW DELHI - India's Supreme Court Wednesday upheld the death penalty given to Mohammed Amir Ajmal Kasab, the lone surviving gunman in the 2008 Mumbai terror attacks.

The death sentence was confirmed by Bombay high court on February 21, 2011 and first delivered by a special court in Mumbai on May 6, 2010 after convicting him of waging war against India and other dozens of charges including murders and terrorist act.

An apex court bench of Justice Aftab Alam and Justice C.K. Prasad reserved the verdict on the conclusion of arguments.

Kasab contended that he was denied a fair trial as he was not provided legal assistance as mandated in terms of Indian constitution. This argument was rejected by the court.
