Notwithstanding Pakistan's insistence on resumption of dialogue, India on Tuesday made it clear that talks cannot take place till it shows seriousness about acting against perpetrators of 26/11 attacks and dismantling of terror infrastructure.

"Our position has been very clear and consistent. We have asked Pakistan to take two steps - one, to bring perpetrators of Mumbai attacks to justice and to ensure that terror structures in Pakistan used against our country should be dismantled," Minister of State for External Affairs Shashi Tharoor told reporters here.
