Seeking severest possible sentence for six persons convicted last week in the 1993 Mumbai serial terror blasts, the prosecution on Thursday told an anti-terror court in Mumbai that many civilized countries have death penalty for such offences. <br/><br/>Special CBI counsel Deepak Salvi urged that while deciding the sentence, the court should keep in mind that 257 people had died and 713 injured in the 1993 Mumbai serial blasts. Salvi said that these two figures of the dead and injured are sufficient to show the brutality of the crime. Salvi added that the quantity of RDX 1,500 kg smuggled in by the conspirators was enough to reduce entire Mumbai to ashes.<br/><br/>The anti-terror court set up under the Terrorist and Disruptive Activities (Prevention) Act cases, had last week convicted six persons including gangsters Abu Salem and Mustafa Dossa in the case, 24 years after the blasts. The court is now hearing arguments on quantum of sentence.<br/>
