UNITED NATIONS - The UN commission inquiring into the assassination of former prime minister Benazir Bhutto met President Asif Ali Zardari Friday as it prepared to leave for Pakistan to continue the probe into the 2007 tragedy, Interior Minister Rehman Malik said. Malik, who spoke to the journalists, said it had made good progress. The commission, which is headed by Chiles UN Ambassador Heraldo Munoz, leaves for Islamabad on Monday. Other members of the commission are: Indonesian attorney general Marzuki Darusman and Irelands former deputy police commissioner Peter Fitzgerald. During his forthcoming visit to Pakistan, the commission will meet, among others, PLM-N Chief Nawaz Sharif, the minister said. Asked whether the commission plans to interview former president Pervez Musharraf, Malik said it had already been to London where the meeting with the retired general could not take place. But he was confident that the commission would ultimately interview him. The commission, which began its probe on July 1, is set to submit its report to the secretary-general sometime in December. Ban will then share the report with the government and submit it to the Security Council for information. The Pakistan government had requested the United Nations to establish a commission to investigate the BBs killing. It has already paid 1.8 million dollars to the UN as seed money to cover its initial costs, and more countries are likely to contribute. During his address to the General Assembly on Friday, President Zardari thanked Secretary-General Ban Ki-moon for constituting the commission. We are confident that the Commission will bring out all dimensions of her (Benazir Bhuttos) life, work and tragic assassination, he said. Menawhile Munoz, the chairman, has said that the commission will contribute to justice the Pakistani authorities are seeking by identifying facts and circumstances of the assassination.
