A senior Pakistani diplomat said the Mumbai attacks were not planned in Pakistan and suggested Friday that India's evidence linking Pakistan-based militants to the deadly siege could be fabricated.

The comments from Wajid Shamsul Hasan, Pakistan's high commissioner to Britain, were the first from a senior Pakistani official since India handed over a dossier of evidence earlier this month that New Delhi said proved the November siege that left 164 dead had been plotted from Pakistan.

"Pakistani territory was not used so far as the investigators have made their conclusions," Hasan told India's NDTV news channel in an interview. "It could have been some other place."

India's package of evidence included details from extensive interrogations of the lone surviving gunman and information gleaned from satellite phones used by the attackers, as well as details of weapons recovered and supplies used.

Pakistan has not yet officially responded to the dossier, but Hasan indicated that Pakistan did not accept the evidence.

"Well, it could be fabricated," he said. Referring to India, he added, "You took 45 days to give that sort of evidence although you started blaming Pakistan from day one."

Hasan said Pakistani authorities would undertake a serious investigation into the attacks.

"We are not going to do any whitewashing business. We believe in going after facts. Our findings will be acceptable to the world," he said. "We will try to satisfy India with our findings. We are addressing the concerns of the world, not just India."

Hasan said he was confident the international community would accept Pakistan's findings.

Since the attacks across India's financial capital, New Delhi has said that it expects Islamabad to crack down on the terrorist network it says operates across the border and to help prosecute anyone involved in the Mumbai

Pakistan has arrested several senior members of Lashkar-e-Taiba, the militant group India blames for the attack, but says it will try any suspects in Pakistani courts. Authorities have also moved against a charity that India and others say is a front for Lashkar.

Pakistani authorities have acknowledged that Mohammed Ajmal Kasab, the only gunmen among the 10 militant to survive the siege, is from Pakistan.

Officials in New Delhi and Islamabad did not immediately comment on Hasan's interview.
