New Delhi/Islamabad, Aug 18 - As Pakistan asked India to share information on fresh terror threats, New Delhi Tuesday said unless Islamabad takes credible action against the 26/11 suspects, it will be 'extremely difficult' to resume meaningful talks.

India also underlined that it has already 'shared solid proof of possible terror attacks' from the Pakistani territory.

'Unless visible and credible action is taken against the perpetrators of the Mumbai attacks, it will be extremely difficult to hold any meaningful talks with Pakistan,' External Affairs Minister S.M. Krishna said on the sidelines of a function held to release a book on India's foreign policy.

'The prime minister has made his position clear,' Krishna said when asked about Prime Minister Manmohan Singh's remarks Monday about Pakistan-based terrorists plotting attacks against India.

'We are hoping that the perpetrators of 26/11 will be brought to justice,' Krishna said.

The book, 'India's Foreign Relations - 2008 Documents', is dedicated to the memory of V. Venkateswara Rao and Brigadier R.D. Mehta, Indian diplomats who were killed in an attack on the Indian embassy in Kabul July 7, 2008.

The attack was blamed on Pakistan-backed Taliban militants, which put the India-Pakistan composite dialogue under stress.

Krishna's remarks came hours after Pakistan asked India to share information on fresh terror threats.
