India will respond to info sought by Pak: Mukherjee

India on Monday, promised to respond to any information sought by Pakistan in connection with probe into the Mumbai attacks but underlined that the request should come through official channels only.

External affairs minister Pranab Mukherjee said India will cooperate "as and when" necessary but ruled out a joint investigation in the attacks.

"Whatever information we get from Pakistan, we respond to it. But information must be made available through official channels and not through media," he told reporters here.

He said India is ready to cooperate with Pakistan "as and when it is necessary" in its investigation into the Mumbai attacks and in this direction referred to the material provided to Islamabad about linkages in that country.

"As far as joint investigation is concerned, I have told you we are having investigation," he said.

After being provided the dossier of evidence on Mumbai attacks, Pakistan has sought more information and in this regard given a list of 30 questions.

India has said it is examining it and will provide whatever information is possible.

Mukherjee made the statement as Pakistan's High commissioner Shahid Malik met foreign secretary Shivshankar Menon to discuss aspects related to the Mumbai attacks.
