But Islamabad said it was not to blame, and, in an unprecedented step, agreed to let the head of the Pakistani military's Inter Services Intelligence (ISI) agency go to India to share information.

On Thursday, Indian Prime Minister Manmohan Singh pinned the blame for the Mumbai attacks on militant groups based in India's neighbours, usually an allusion to old rival Pakistan.

Indian Foreign Minister Pranab Mukherjee was more explicit on Friday. "Preliminary evidence, prima facie evidence, indicates elements with links to Pakistan are involved," Mukherjee told a news conference in New Delhi.
