UNITED NATIONS - 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 U.N. spokesperson said Thursday. 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 Dec. 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 Chile's U.N. Ambassador Heraldo Muoz, includes Indonesia's 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.
