ISLAMABAD: US investigators have concluded after interrogating the lone captured suspect, Ajmal Amir Kasab, that the Inter-Services Intelligence is not involved in the Mumbai attacks.

Diplomats said agents of the Federal Bureau of Investigation were allowed to interrogate Kasab for nine hours during which they had established that he was a Pakistan national.

The sources said that FBI investigators had also reached a conclusion that the attackers had come to Mumbai from Pakistan. The plan was hatched in Pakistan and terrorists were provided necessary training by Laskar-e-Taiba, according to the investigators.

The US and UK are citing the Indian example and pressuring Pakistan to allow their investigators to interrogate the suspects arrested by Pakistani authorities. The US is also urging Pakistan government to rein in ISI because of its “previous involvement in questionable activities”.
