A day after India handed over answers to the 30 questions asked by Pakistan, on the terror attack in Mumbai [Images] last November, External Affairs Minister Pranab Mukherjee [Images] on Saturday said he expected Islamabad [Images] to follow up its commitment with 'tangible action'.

"Words and commitments should be followed by tangible action," he told reporters when asked whether he was satisfied with Pakistan's handling of the investigation into the Mumbai attacks.

Mukherjee pointed out that India has been urging Pakistan to dismantle the terror infrastructure on its soil, hand over fugitives hiding there and bring the perpetrators of the Mumbai terror strikes to justice.

"The question is not (about) objective satisfaction or dissatisfaction. It is a question of certain hard facts," he said.
