Alleged Mumbai terrorists
Ismail Khan, alias Abu Ismail, was reportedly the companion of alleged Mumbai gunman Mohammad Ajmal Amir ‘Kasab’.
DNA samples are being used in evidence.
Reportedly, the DNA samples provided by India for Ajmal and Ismail are identical and there is only a one-in-a-trillion chance of this happening in the case of twins.
"Media reports had said that in a dossier sent to Pakistan the DNA reports of arrested terrorist Mohammed Ajmal Kasab and the slain terrorist Abu Ismail were identical."
