NEW DELHI: External Affairs Minister Pranab Mukherjee told NDTV on Thursday that Pakistan is yet to demonstrate “tangible” action against the perpetrators of the Mumbai attacks though it was obliged to do so under international laws.

Top LeT commander Zarar Shah, according to U.S. media, confessed to the group’s involvement in the attacks and the U.S. provided Islamabad with the tape of a conversation his associate Zakiur Rahman Lakhvi, the alleged mastermind, had with the attackers.

Asked whether an extradition treaty was needed for Islamabad to hand over the attackers, he said, “An extradition treaty is not required to take action on these matters” as Pakistan is party to various international conventions and arrangements starting from SAARC to various international conventions against taking hostages, and conventions against bombings.

Mr. Mukherjee said: “So far as the desired results are concerned, the taste of the pudding is in the eating. What we are asking Pakistan to do, requesting them [is] to fulfil their own commitments which they have made to our Prime Minister twice” on January 6, 2004 and in September last year.

“Up till now, we have not seen tangible and credible action taken by Pakistan.”

To a question, he said, “We have not created any war hysteria. In our utterances, in our action, there is no question of creating any war hysteria or war cry.” Referring to remarks by Pakistan Foreign Minister Shah Mehmood Qureshi that India should de-escalate tension, Mr. Mukherjee said, “We have not escalated the tension. So, where is the question of our de-escalation.” — PTI
