Krishna said India would 'appeal to our friends across the board to prevail on Pakistan to see the part of reason and bring to justice all those behind the attack on Mumbai.'

He suggested that if India were attacked again it might not show the same restraint against Pakistan. 'I hope there won't be any attacks, but if there is an attack on India, India is fully prepared to meet [it],' he said.

Terror on both the east and western borders of Pakistan will be atop the agenda when Krishna meets Pakistan's Foreign Minister Shah Mehmood Qureshi on Saturday in New York.

The terrorist attack that killed 166 people in Mumbai last November will be India's 'focal point' of the talks, Krishna said.
