India and Pakistan on Thursday agreed not to link the composite dialogue to action on terrorism as Prime Minister Manmohan Singh elicited a promise from his counterpart Yousuf Raza Gilani that Islamabad would "do everything in its power" to punish perpetrators of 26/11 attack.

Prime Minister Singh had on Wednesday made a strong pitch for dismantling of terror infrastructure and asked countries not to provide safe havens for terrorists.

In recent years, terrorist groups have become more sophisticated, more organised and more daring. Terrorists and those who aid and abet them must be brought to justice," he said, addressing the plenary session of the two-day summit of the 118-member NAM, where his Pakistani counterpart was also present.

The discussions between the two top leaders are also believed to have covered the flip-flop in Pakistan over the detention and release of Jamaat-ud-Dawa chief Hafiz Mohammad Saeed, a key accused in the Mumbai terror attacks.

The meeting between Dr Singh and Gilani comes six days after Pakistan handed over a fresh dossier on its probe into the Mumbai terror attacks to India.
