Benazir Bhutto's son calls for UN probe of her murder

Benazir Bhutto's son on Tuesday called for a UN sponsored investigation of her murder, saying that he does not trust officials in Pakistan. "We do not believe that an investigation under the authority of the Pakistani government has the necessary transparency," Bilawal Bhutto Zardari told a news conference. "Already so much forensic evidence has been destroyed." The 19-year-old Oxford University student was chosen to succeed his mother as leader of the Pakistan People's Party, though day-to-day leadership is in the hands of his father, Asif Ali Zardari. "It was recognized at this moment of crisis that the party needed a close association with my mother through the blood line," said Bilawal Bhutto Zardari.
