Pakistan's Inter-Services Intelligence (ISI) agency has "given its feedback" to India about the Mumbai attacks, prime minister Yousuf Raza Gilani said on Friday, media reports said.

Gilani's remarks came shortly before US vice-president-elect Joe Biden arrived here for talks with the Pakistani leadership on the tensions with India in the wake of the carnage in Mumbai, reported a tv news channel.

"India has given 52 pages to the CIA and our ISI (Inter-Services Intelligence) has given its feedback and information sharing. That has been passed on to India," Gilani said.

The prime minister said Pakistan and the US' Central Intelligence Agency had had a good working relationship in the past, adding: "If some other information is needed, we are ready for cooperation."

"The world must not let tensions between India and Pakistan escalate," Gilani said earlier as he opened a seminar on democracy.

Gilani said India had rejected Pakistan's proposals for cooperation on the investigation into the attacks, which New Delhi has blamed on Lashkar-e-Taiba.
