"If Pakistan government says that it can't investigate why don't they let the FBI to investigate who are willing to do it. If they can't investigate, allow us (India) to do the investigation," Chidambaram said at a press conference in Ahmedabad.

He was referring to reports of Pakistan Interior Minister Rehman Malik complaining that he did not have enough evidence to investigate the 26/11 attack case.

"Pakistan Interior Minister has the habit of saying every 15 days that there is not enough evidence. If the government of a country is not going to investigate I can only feel sorry for them," he said.

The evidence in India has already been investigated and remaining evidence is in Pakistan and is yet to be looked into, he said.

Malik had recently said that evidence provided by India was not enough. On November 26 last year, ten terrorists had set sail from Karachi and arrived on Mumbai shores to carry out attacks in which 183 people were killed.

'DNA goof-up a non-issue'

Union Home Minister P Chidambaram said that the possible goof-up in sending identical DNA reports of terrorists involved in 26/11 attack in Mumbai was a "non-issue" and a "minor clerical error".

"Pakistan no longer denies that Mohammed Ajmal Kasab and Abu Ismail (the two terrorists involved in the Mumbai terror strikes) were its nationals," Chidambaram said alluding that the goof-up may have occurred because the same photocopies of the report might have been sent.

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.
