UNITED NATIONS-The UN Commission inquiring into the assassination of former Prime Minister Benazir Bhutto is seeking a meeting with former President Pervez Musharraf during an upcoming visit to London in pursuit of its mandate to identify the facts and circumstances behind the December 2007 tragedy, according to informed sources. The sources said the commission plans to visit the British capital and Washington within a couple of weeks. The three-member commission, which is led by Chiles UN Ambassador Heraldo Munoz, paid a visit in July to Pakistan where it called on President Asif Ali Zardari and held talks with other govt leaders and officials. The commission left behind its seven experts to carry on the investigations. Recently they visited Rawalpindis Liaquat Bagh where Benazir Bhutto was killed. In London, the sources said the commission will visit the headquarters of Scotland Yard, whose investigators submitted a report in February after a 2-1/2 week investigation of the assassination. The British experts said that Benazir Bhutto was killed by the force of a suicide bomb and not by an assassins bullet, a conclusion not accepted by her supporters, other Pakistanis and medical experts. After PPP swept to power, it turned to the UN for investigations. The commission is known to believe that its work will be incomplete without interviewing the most authoritative personality in Pakistan when Benazir Bhutto was murdered-Gen (Retd) Pervez Musharraf, who now resides in London. The commission will also interview in London Ms. Nahid Khan, a close associate of the PPP leader. In Washington, the commission will also meet officials of various intelligence agencies. In addition, the commission will interview CNNs Wolf Blitzer, who reportedly received an e-mail through Benazir Bhuttos confidant in Washington, Mark Siegal, saying if anything happened to her she would hold Musharraf 'responsible because his govt did not do enough to provide for her security. The commission will also speak to Siegal, a longtime spokesman for Benazir Bhutto. The Commission, which began its work on July 1, will submit a report to Secretary-General Ban ki-moon within six months. Ban will then share the report with the govt and submit it to the Security Council for information.
