In a new twist, the UN Commission, probing into the assassination of Pakistan's former Prime Minister Benazir Bhutto, is now suspecting involvement of Pakistani soldiers in the plot.
Pakistani officials said they were searching for four military personnel who had disappeared just before the suicide attack on Bhutto during an election rally in Rawalpindi in December 2007.
The missing soldiers were retired army personnel who were among the eight army men related to the main accused and a proclaimed offender in the case Ibad Ur Rehman, interior ministry officials said.
The investigators were facing difficulties in determining the exact status of these soldiers and so far no record had been provided. The four other soldiers are still serving the army, the officials told DawnNews.
The four missing army personnel had never been mentioned before in the legal proceedings.
Pakistan had sought a UN probe a year ago after its own investigations and those by Scotland Yard failed to make headway into Bhutto's killing Dec 27, 2007 in a gun and bomb attack as she left a political rally in the garrison town of Rawalpindi.
The four-member probe commission which was constituted in June last year is expected to submit its report by the end of this month.
