Hambali is alleged to have been the leader of Jemaah Islamiyah, a South-east Asian affiliate of al-Qaeda. The Pentagon said in a brief statement on the case that he was accused with Mohammed Nazir Bin Lep and Mohammed Farik Bin Amin, who are from Malaysia, of planning and aiding the attacks.
All three were captured in Thailand in 2003 and held in CIA custody before they were taken to Guantanamo three years later.
The Bali bombings killed 88 Australians among 202 tourists and locals.
