Headley's confession may help nail Pakistan: BJP

New Delhi, March 19 : Lashkar-e-Taiba operative David Headley's confession about his involvement in the Mumbai terror attack would add weight to New Delhi's claims of Pakistan's involvement in terrorist acts against India, the Bharatiya Janata Party (BJP) said Friday.

"It will be very clear to the world community that Pakistan is involved in the terror attacks against India after Headley has pleaded guilty to 26/11," BJP spokesperson Prakash Javadekar told IANS.

He said though the confessional statement of the Pakistan-born American had ruled out the possibility of his extradition to India, "there are still chances that (Indian investigators) can question" him.

"We cannot get him extradited. But we can get access to him to question him. The dossiers (India has given to Pakistan about terrorists operating from its soil) will be more weighty," the BJP leader said.

Headley pleaded guilty in a Chicago court Thursday to a dozen federal terrorism charges and admitted his role in planning the 2008 Mumbai terror attacks that left 166 people dead.
