Expressing his shock and outrage at the assassination of Pakistani opposition leader Benazir Bhutto, U.N. Secretary-General Ban Ki-moon on Thursday strongly condemned the “heinous crime” and called for those responsible for the attack to be brought to justice. The assassination of former Prime Minister Benazir Bhutto “represents an assault on stability in Pakistan and its democratic process,” Ban said in a statement issued by his office. “While strongly urging calm and restraint to be maintained at this difficult time, I call on all Pakistanis to work together for peace and national unity.” The secretary-general also conveyed his condolences to Benazir Bhutto's family and colleagues, as well as to the people of Pakistan.
