He also ruled out setting up a commission of inquiry into the 26/11 attack.

"This is a minor clerical error which can be corrected. Kasab is still alive. His DNA can be taken again while a dead man's DNA is required only to know who the father or mother is," he said.

While Kasab is the lone gunman captured alive in the 26/11 attack, Ismail was among the nine terrorists killed in the operation by commandos.

The 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.

DNA reports of both Ismail and Kasab are with the Mumbai police, Chidambaram said, adding that there was no need for commission of enquiry for 26/11 attack.
