Indicating the hardening Indian stand, Krishna said Pakistan has a vested interest in blocking the inquiry into the 26/11 attacks and safeguarding terror mastermind Hafiz Saeed.

'It is in our vital interest to normalise our relations with Pakistan. However, we are at a stage where it is for Pakistan to determine the kind of relationship it wants to have with India,' said Krishna.

'The Mumbai attack was launched from Pakistan and the conspiracy behind the attack was hatched there. Clearly the onus is on Pakistan to unveil the conspiracy,' he said.

Reminding Pakistan of its anti-terror pledge, Krishna said: 'Let me emphasise that it is our considered position that there should be concrete action against those guilty of the Mumbai terrorist attack before there can be any meaningful dialogue with Pakistan,' he said.

'Until the Mumbai attack, India was conducting the composite dialogue with utmost sincerity. But we cannot have terrorism and negotiations at the same time,' Krishna said.

'Pakistan has to prove its credentials by implementing its assurances,' he emphasised.

Krishna's tough talk restores the link between Pakistan's action against anti-India terror and composite dialogue that some thought was delinked in the Sharm el Sheikh joint statement.

In an interview with the Headlines Today, Krishna said: 'It's an orchestrated voice emanating from Pakistan. They have a vested interest in safeguarding Hafiz Saeed. We have no doubt that Saeed is the brain behind the 26/11 attacks and have evidence to prove it.'
