ISLAMABAD - A six-member technical assessment team of the United Nations, which met the Advisor to Prime Minister on Interior Rehman Malik on Wednesday, has extended its stay in Pakistan for one day to complete the assigned task. The team was previously scheduled to leave the country on Friday. According to the official sources, the Interior Advisor briefed the visiting delegation of the security arrangements made for the safety and protection of the members of the UN Commission coming to probe into the Benazir murder case. The delegation headed by Mark Quarterman also appreciated the security cover provided to them during their stay in the country. Police chiefs of Rawalpindi and Islamabad were directed to make VVIP security arrangements for the visiting UN team. They were also told to arrange bullet-proof vehicles for them. The team will visit Liaquat Bagh, the place where Benazir Bhutto was assassinated on Dec 27, 2007. A senior security official also said the UN team would hold talks with officials of the Ministry of Foreign Affairs as well as officials of the intelligence agencies. The UN fact-finding mission is likely to start its investigation into Benazirs assassination by the first week of the next month, the source added. The visiting team will prepare a report on the technical and security assistance, later to be handed over to the central commission. The UN Secretary-General Ban Ki-moon had announced on February 4 a fact-finding mission into the assassination of Benazir Bhutto. Special Correspondent from United Nations adds: A UN technical team is to report to Secretary-General Ban Ki-moon soon on its preparatory work in Pakistan for the international fact-finding commission to probe the assassination of Benazir Bhutto, a UN spokesperson said Wednesday. Michele Montas, the spokesperson, told the regular news briefing that the team, which is headed by Mark Quaterman and currently in Islamabad, will return to New York next week. Ms Bhutto was assassinated in gunshot and suicide bombing attacks on December 27, 2007 after addressing an election rally in a park in Rawalpindi. The Pakistani government had requested the United Nations to establish a commission to investigate the killing. In February, the UN Chief decided to establish a three-member panel to investigate the assassination, which plunged Pakistan in grief. The commission, which will be headed by Chiles UN Ambassador Heraldo Muoz, includes Indonesias Marzuki Dar Usman. But no decision has been made on its third member. He or she will be either from Sweden or Norway. No date has been set for the start of the probe by the commission.
