The Foreign Secretary Mrs. Nirupama Rao has asserted that justice will be done only when the perpetrators of Mumbai terror attacks are brought to the book. Mrs. Rao told this to newsmen in reply to a query whether she will raise this issue when she meets her Pakistani counterpart in Bhutan. She was talking to newsmen following her meeting with the Home Minister Mr. P. Chidambaram in New Delhi this evening. The Foreign Secretary, who is leaving for Thimphu for a SAARC meeting, will hold bilateral talks with her Pakistani counterpart Salman Bashir on the margins of Sunday and Monday. Noting that 26/11 trial in Pakistan was one of the issues under discussion between the two governments, particularly between the Interior Ministry of Pakistan and our Home ministry, she said New Delhi and Islamabad have been in correspondence about the exchange of evidence that is required for the trial to go forward after the meeting of the ministers last June. Commenting on her forthcoming meeting with Bashir, she said India will see how it can pick up the thread once again.
