But the United Nations, which boycotted the truth commission, has said it will continue to back prosecutions through the Serious Crime Unit, which it set up to assist East Timor's prosecutors' office in probing the violence in which the United Nations says about 1,000 East Timorese died.
Several Indonesian military officials were tried in Indonesian human rights courts following the 1999 violence, but none were convicted.
'Bringing them back from Indonesia depends on bilateral agreements on extraditions. It depends also on the will of Indonesian authorities,' Marek Michon, chief investigator of the U.N. body, told reporters.
Michon said it had submitted 20 cases to East Timor's prosecutors' office, while it could take three years to conclude all 396 cases.
