The FBI has admitted that it has been in touch with Pakistan as it investigates the terror attacks that were allegedly being planned by David Coleman Headley and top operatives of the Lashkar-e-Toiba (LeT).

But on Friday, Prime Minister Manmohan Singh said, "Well, to the extent that I have information, I don't think this Headley affair, we have received any information from the Pakistan side."

Headley was arrested in Chicago by the FBI last month, along with Tahhawaur Hussain Rana, a Pakistan-born Canadian. Headley, an American citizen who spent considerable time in Pakistan met Rana there. The FBI says that it has evidence to suggest that Headley was planning a  terror strike against Delhi, specifically at the National Defence College.

An Indian team of intelligence officials is now in America interrogating Headley.  But the Pakistani angle could be  new source of tension.  On Friday, when asked if the government accepts there is Pakistani connection to Headley's plot, Home Minister P Chidambaram responded decisively, "Of course there is...that's why the FBI has named it  in its affidavit and two people have been arrested."

What is clear is that the  plot  is turning out to be to be larger than initially believed.  Based on information provided by Headley and Rana, suspected Lashkar terrorists have now been arrested in Bangladesh. They were allegedly planning attacks on US and other embassies in Dhaka.
