Nikam said that Kasab's confession he made Monday has not been accepted since he has not divulged the complete truth about the conspiracy behind the terrorist strike.
'Accordingly, the court has ruled that the trial will continue as usual. So far, the prosecution has examined 134 witnesses in the case and we shall produce more witnesses before the court,' Nikam told reporters.
He told the court that the prosecution needed some more time to unravel the 26/11 conspiracy, the motives behind killing so many people, including foreigners, and other missing links in the terror attacks.
On Wednesday Kasab dramatically pleaded before the court that he accepted all his crimes and should be hanged.
His plea in the open court came two days after his confession in which he gave a chilling blow-by-blow account of his role in the terror attacks which left over 170 people dead.
Kasab said his confession was made voluntarily and without any pressures or external influence. He also denied the prosecution charge that he was making the confession to escape with a lighter punishment.
