The prosecution today sought death penalty for Pakistani gunman Ajmal Amir Kasab, convicted for 26/11 terror attacks. Terming Kasab's case as the rarest of rare, public prosecutor Ujjwal Nikam told the anti-terror court, such a monster should be given death penalty. He also described him as a killing machine manufactured in Pakistan who had total disregard for life. Nikam said in his arguments over quantum of sentence to the terrorist that if Kasab is given lesser punishment, India will become a soft target for every self-styled terror group. The arguments were made a day after Special Judge M L Tahaliyani found Kasab guilty of mass murder and waging war against India. Seeking death for the 22-year-old lone surviving gunman involved in the brazen attacks that left 166 people dead, Nikam said, Kasab has lost every right to live. Nikam added that he was not happy after killing 72 persons and wanted to kill more.<br/>
