India's Supreme Court has upheld the death sentence of the lone survivor of a group of militants who attacked the country's financial capital, Mumbai, in 2008 killing 166 people. A Mumbai court had convicted 22-year-old Mohammed Ajmal Kasab of murder, waging war against India, conspiracy and terrorism in May 2010 and sentenced him to death. The sentence was confirmed by the state High Court in February last year. Legally, he can still appeal to India's president for mercy, according to a report of the Associated Press.
