Earlier, FBI sleuths had concluded after questioning Kasab for nine hours in India that he was a Pakistani and that the Mumbai attacks were planned and coordinated by the Pakistan-based elements, including Lashkar-e-Toiba operations commander Zakiur Rehman Lakhvi.

Kasab's father has admitted in an interview to 'Dawn' that the gunman, whose pictures were beamed around the world by the media, was his son.

Other residents of Faridkot told Geo News channel that Iman had last visited the village about six months ago, when he told his mother he was going away for 'jehad'.

The FBI has registered a case regarding the Mumbai attacks as the US laws require the agency to file charges in case of the death or torture of any American national outside the country.

The Director of US National Intelligence, John Michael McConnell, too visited India to assist in the probe into the Mumbai attacks.
