Amid reports that Pakistan may seek custody of Indian nationals in connection with the Samjhauta Express case, India on Tuesday said it would be better if there is no diversion at this stage as the whole world was watching actions by Islamabad to dismantle terror infrastructure.

"It would be better if there is no diversion or deflection at this stage," Minister of State for External Affairs Anand Sharma said when asked to comment on reports that Pakistan may seek Colonel Purohit's custody in connection with the Samjhauta Express case.

"I think we are talking about what is firmly established about the dastardly attack in Mumbai carried out by organisations which have been identified and named and individuals who are nationals of Pakistan," he said.

On Pakistan's offer to India to join the probe into the Mumbai attacks, Sharma said Pakistan should first disclose what their investigation revealed.

"I have to say that the whole world is watching how effective actions would be to dismantle the infrastructure of terrorism and also bring to justice those who are responsible for masterminding the carnage in Mumbai," he said.
