NEW DELHI, OCTOBER 24: Prime Minister Manmohan Singh today said there was “credible evidence” of Pakistani involvement in the July 11 train blasts in Mumbai.

“All I can say is that there is credible evidence”, he told reporters when asked about the comments made by NSA MK Narayanan that there was “pretty good” but not “clinching” evidence of ISI’s involvement even as Union Home Secretary VK Duggal spoke of “fairly solid” evidence.

On the Indo-Pak Joint Mechanism to fight terrorism, the PM said “it is a trial”. “We have to experiment...we have to talk as we are not going to war with Pakistan”.

Defence Minister Pranab Mukherjee, who is the new External Affairs Minister, said India would share information with Pakistan regarding the blasts and see the response.

“We will exchange information with Pakistan. After that we have to see how they react,” he said.
