New Delhi/Islamabad, Sep. 4 : Union Home Minister P. Chidamabaram has told a private television channel that he may not respond to further demands from the Pakistan Government for information on the 26/11 attacks on Mumbai.

Stating that the process has reached a point of exhaustion and with no tangibel results, Chidambaram said Islamabad''s description of India''s sixth dossier on the attack as a ''Rehash'' could be the last straw as far as New Delhi is concerned.

Chidambaram''s comments came as Pakistan''s Interior Minister Rehman Malik said on Thursday that the latest dossier provided by India on the Mumbai attacks as a "rehash of information" contained in previous documents, indicating that it is inadequate for taking action against LeT founder Hafiz Mohammad Saeed.

"The last dossier from India was a rehash of information received in previous dossiers," Foreign Office spokesman Abdul Basit also told a weekly news briefing.

The spokesman did not say how Pakistan intended to deal with Saeed, for whom Interpol recently issued a Red Corner Notice.

The trial of suspects arrested by Pakistani authorities in connection with the Mumbai attacks is proceeding and Islamabad is "serious about bringing the perpetrators to book," Basit said.

At the same time, he said, Pakistan "still believes that the composite dialogue is the only way forward." He also made it clear that if the stalled dialogue were to be resumed, "it would not be a favour to Pakistan because talks and exchange of views is the only way" to improve ties between the two sides.
