Former two-time premier Bhutto was killed in a gun and bombing attack in Rawalpindi on December 27, 2007 when she came out of park after addressing an election rally.
Two policeman responsible for guarding her at the event in Rawalpindi were found guilty of negligence and sentenced to 17 years each in jail.
2009: Pervez Musharraf, Rawalpindi police chief Saud Aziz and SSP Kurrum Shahezad, among the accused, implicated this year, after fresh probe by Federal Investigation Agency (FIA). He has denied the allegations.
Musharraf was indicted in 2013 on charges of murder, criminal conspiracy to murder and facilitation of murder, but his health problems delayed the case.
He has been in self-imposed exile in Dubai since a travel ban was lifted in March 2016 for health reasons while awaiting trial.
The ATC ordered the seizures of all properties linked to Pervez Musharraf in Pakistan, apart from expediting the process of his extradition.
The judge acquitted the five suspects for lack of evidence although they had confessed during the investigation, Prosecutor Khawaja Imtiaz said.
"This time in their lives can not be brought back, but we thank Allah that they have been declared innocent".
The PPP is now led by Ms. Bhutto's son Bilawal, but earlier this year Ms. Khan applied to Pakistan's Supreme Court in a bid to register the name PPP for her own political party. The PPP will also employ legal instruments to mount its claim to become a party to the case and file an appeal against the verdict. Bhutto's daughter Aseefa Zardari tweeted moments after the court's announcement.
Senior officer Khurram Shahzad was accused of hosing down the scene less than two hours after the killing.
Musharraf was also among the list of accused, who is living in exile in Britain and the United Arab Emirates. They were also ordered to pay a fine of Rs. 0.5 million each.
Musharraf's government blamed Bhutto's killing on Pakistani Taliban chief Baitullah Mehsud, who was killed in a US drone attack in 2009. At least 23 other people were also killed in that attack.
The Party recalls the apprehensions expressed by Shaheed Mohtarma Benazir about the plot to assassinate her.
"Were they Taliban or Musharraf", he said, adding the prosecution "could not provide any evidence".
Responsibility for the assassination remains shrouded in mystery. "Eight judges in the Anti-Terrorism Court have changed since 2008", he told Sputnik.
