Muammar Gaddafi's son and more than 30 others, including his prime minister and intelligence chief, have been sent for trial before a higher court on charges ranging from murder and treason to looting during Libya's 2011 uprising.
Prosecutor Al-Seddik al-Sur said after a hearing today that the lower court also decided to appoint defence lawyers for Gaddafi's son, Saif al-Islam, and the late dictator's intelligence chief, Abdullah al-Senoussi.
He did not announce a date for the trial before the Criminal Court.
Al-Senouusi and al-Baghdadi al-Mahmoudi, Gaddafi's last prime minister, attended the hearing, but not Saif al-Islam, held by a militia group that captured him as he attempted to flee to neighbouring Niger in 2011.
Gaddafi's 42-year rule ended in 2011.
