The son of deposed Libyan leader Muammar Gaddafi, Saif al-Islam, has briefly appeared in court in the town of Zintan to face criminal charges.
The case relates to a visit last year from an Australian lawyer from the International Criminal Court who was accused of passing information to Gaddafi.
He faces charges of complicity in exchanging information, obtaining documents that threaten national security, and insulting the national flag.
Saif has also been indicted for war crimes committed during the 2011 uprising. Both Libya and the ICC claim jurisdiction for that trial.
The the BBC reports that when asked whether he was in good health, Saif said that he was and gave a thumbs-up sign.
The trial was postponed until 19 September.
In June last year, ICC lawyer Melinda Taylor and three other ICC personnel were arrested and held for the three weeks after visiting Saif.
Ms Taylor was accused of clandestinely passing him a coded letter from a fugitive former aide, Mohammed Ismail.
The four were subsequently released to The Hague and are not expected to return to Libya.
Saif has been held in Zintan since a brigade from the town captured him in November 2011.
