A gunman involved in the deadly Mumbai terror attacks erupted into laughter Monday when asked by a court if he understood the charges against him, the Times of London reported.

Twenty-one-year old Mohammed Ajmal Amir Kasab was one of ten terrorists who killed 170 people last November in India's financial capital. The Pakistani national, who faces death by hanging if convicted of murder, was the only gunman to be caught alive.

"Kasab was smiling throughout the hearing and said that he was from Pakistan,” special public prosecutor Ujjwal Nikam reportedly told the Times of London.

“He laughed when the judge asked him if he understood everything in the charge sheet," Nikam said, according to the newspaper.
