Giving a new twist to probe into Mumbai [Images] attacks, Pakistan is now alleging that there were 'elements in India' who helped in carrying out the strikes and wants its investigators to be provided access to them.

'There is a strong realisation in Pakistani security agencies that without the help of elements in India, the Mumbai crime could have not been committed,' official sources were quoted as saying by the Dawn newspaper on Tuesday.

In what could further delay the prosecution of Mumbai attackers, the paper said Pakistan is also seeking DNA samples of the terrorists involved in the strikes and more information about contacts made by them through the internet.

The Pakistani investigation report into the Mumbai attacks, which was reviewed yesterday at a meeting of the Defence Committee of the Cabinet chaired by Prime Minister Yousuf Raza Gilani [Images], would be sent to New Delhi [Images] in a couple of days, the paper quoted these officials.

In its report, Pakistan has sought results of DNA tests on Ajmal Kasab [Images] and the nine other attackers killed by Indian security forces so that these could be matched with their family members, if any, in Pakistan, the sources said.

Pakistan wants information about weapons used by the terrorists and details of mobile phone calls made by them and taped by Indian security agencies.

Pakistan also wants information regarding IP addresses from which emails were sent to attackers by the alleged perpetrators, the sources said.

It wants India to provide details about people who were reportedly killed by the terrorists when they illegally entered the country's territorial waters.

The Pakistan government had on Monday decided to register a case against the perpetrators of the Mumbai attacks to bring them to justice in accordance with Pakistani laws.

An FIR would be registered in a 'couple of days' and this would also make the contents of the Pakistani report public, the paper said quoting sources.

The government has described the information provided by India as 'insufficient' to reach a logical conclusion and to bring the perpetrators to justice.

An official statement issued on Monday said further queries would soon be sent to India.
