Terrorism will be the single most important issue for discussion between Indian External Affairs Minister S M Krishna and his Pakistani counterpart during their meeting here on Sunday. Terrorism is the single most important issue from our side, Mr. Krishna said ahead of his meeting with Pakistani Foreign Minister Shah Mehmood Qureshi on the sidelines of the United Nations General Assembly. The Minister said the recent action taken against JuD chief Hafiz Saeed, the mastermind of the Mumbai attacks, was not satisfactory. Mr. Krishna pointed out that the reason for Saeeds arrest was not the Mumbai attacks but a hate speech he had made at a Ramadan dinner criticising Pakistan, India and the United States. Mr. Krishna also said New Delhi was assessing Islamabads recent response to its demands related to the Mumbai attacks. We are evaluating the various steps that Pakistan seems to have taken with respect to Mumbai attacks, he said. Pakistan has arrested seven people and sent out an alert for 11 more in connection with the attacks. Indian Foreign Secretary Nirupama Rao will also meet her counterpart Salman Bashir before the Foreign Ministers meeting.
