Credible action is required from Pakistan to deal with terrorists working against India from its territory, Prime Minister Manmohan Singh said Saturday ahead of his meeting with his Pakistani counterpart Yousuf Raza Gilani in Egypt next week.

"I am looking forward to meeting Prime Minister Gilani (in Egypt). I hope that out of that meeting, renewed reaffirmation on part of Pakistan that it will bring perpetrators of the Mumbai massacre to justice and that Pakistan's territory will not used for such activities. If that is done, we are willing to walk more than half the distance," the prime minister told reporters media while returning from Italy after attending the G8-G5 summit.
