'Pak not serious about 26/11 enquiry'

"I did brief them on the State of the trial of Ajmal Kasab in India and I also mention about the no progress in Pakistan, even in respect of the five or six people they have arrested. And Hafeez Sayeed (LeT founder) remains a free man. I think that is enough. They know to draw the lessons from that statement," he said.

Responding to a question, he said the next level of Indo-US relationship does not mean "leaning on" Pakistan. "Next level means many things. The next level means working together on security related matters," he said.

"I think, the US understands the difference between the way India's approach to post-26/11 situation and the way Pakistan approached post-26/11 situation. It is enough to draw attention to the difference and leave it there," he said when asked if the US is exerting enough pressure on Pakistan to take action against terrorists targeting India from its soil.

Chidambaram said when asked about the controversy on the affidavit filed by the Center in the Gujarat High Court in the Ishrat Jahan and the other three encounter case.

"You cannot read into it what it does not say. I think it is self-evident that intelligence inputs are not evidence, much less conclusive proof. They are just inputs. They are shared with governments on a regular basis. That is not evidence. That is not conclusive proof," he argued.

The four persons, claimed to have been killed by the police in an encounter on the outskirts of the city on June15, 2004 were Ishrat, Javed Ghulam Sheikh alias Pranesh Kumar Pillai, Amjad Ali alias Rajkumar Akbar Ali Rana and Jisan Johar Abdul Gani. Gujarat Police had also claimed that the four persons were on a mission to kill Chief Minister Narendra Modi.
