New Delhi, Jan 17 (IANS) A day after he indicated India was willing to accept a trial of fugitives in Pakistan, External Affairs Minister Pranab Mukherjee Friday hardened his posture, saying there was no question of a climbdown and reiterated that the perpetrators of the Mumbai carnage must face Indian justice.

We have never given up the demand that perpetrators of terror acts should be extradited to India. There is no question of that or climbdown, Mukherjee told reporters when asked whether there was a shift in India's demand to Pakistan to extradite the perpetrators of the Mumbai carnage.

However, the fact remains that dastardly terror crimes have been committed in India. Therefore, the perpetrators must face Indian justice, Mukherjee asserted in a bid to counter the impression created by his comments in an interview to Aaj Tak.

This is not an either or situation as these things are not mutually exclusive, he said on a day Pakistan responded to the 26/11 dossier presented by India that linked Pakistani nationals to the Mumbai attacks.

It would be ideal if (they) can hand over the fugitives from India to us. If that is not possible, there should at least be a fair trial of these fugitives in Pakistan, Mukherjee told the news channel Thursday.
