Chaudhry Zulfiqar Ali, a Special Prosecutor with the Federal Investigation Agency, made the remarks while appearing before the Rawalpindi bench of the Lahore High Court.
The FIA has filed a petition asking the High Court to direct an anti-terrorism court to conduct daily hearings in the assassination case.
A two-judge bench of the High Court sought records of the assassination case from the anti-terrorism court.
It also issued notices to the lawyers of the accused to appear before it on February 13.
Special Prosecutor Ali told the court that Bhutto was killed on December 27, 2007 after addressing an election rally in Rawalpindi and it was regrettable that the trial of this high-profile case had not been completed even after five years.
Ali contended that the anti-terrorism court is bound to hold daily hearings of cases for quick disposal.
The FIA said in its petition that the lawyers of the accused were using delaying tactics, which was evident from the fact that no other case is pending in the same anti-terror court since 2007.
The FIA pointed out in its petition that the case related to the assassination of Punjab Governor Salmaan Taseer was decided in just 10 months.
Islamabad: A Pakistani prosecutor today informed a court that it was regrettable that the trial of five suspects charged with involvement in the 2007 killing of former premier Benazir Bhutto had not been completed even after five years.
