MUMBAI -- The man accused of being the lone surviving gunman from last year's Mumbai attack pleaded not guilty yesterday to 86 charges against him, including murder and waging war against India, lawyers said.

"The prosecution today framed 86 charges against the accused, who has pleaded not guilty to all charges," Ujjwal Nikam told reporters after the court was adjourned for the day.

The charges range from waging war to hijacking a boat that carried the attackers to Mumbai.

Kasab faces the death penalty if found guilty.

Police say Kasab was one of 10 gunmen who landed in Mumbai by boat from Pakistan and rampaged through several of the city's landmarks including the main train station, two luxury hotels and a Jewish centre over three days.

Judge M.L. Tahilyani explained the charges to Kasab in Hindi and asked him if he understood, Nikam said. When asked how he pleaded, Kasab said he was not guilty.

Kasab also told the court yesterday he was 21 years old, Nikam said, putting to rest a defense submission that he was a minor and should therefore be tried in juvenile court.

The judge had earlier ordered medical and dental tests to confirm his age.

The prosecution will now begin to present its evidence and witnesses in each of the cases against the accused, Nikam said.

The prosecution has said it has more than 1,800 witnesses and more than 750 pieces of evidence.
