India will seek an affirmative action from Pakistan regarding 26/11 Mumbai terror attacks when it will hold extensive bilateral talks with Pakistan later this week. An Indian delegation led by Foreign Secretary Nirupama Rao will leave for Islamabad on Thursday to hold comprehensive dialogue with her counterpart Salman Bashir. During the talks, India will raise its concerns over terror directed against it from the Pakistani soil. Besides talks on Mumbai attack, all outstanding issues including Jammu and Kashmir are likely to be discussed. Government sources said in New Delhi today that all documents pertaining to Mumbai attacks have been handed over to Pakistan and India expects concrete results from the trials in Pakistan. It was pointed out that India has no objection to a Judicial Commission from Pakistan to visit India. Pakistan is yet to place a formal request in this regard.
