The trial of Saif al-Islam Gaddafi - the son of late Libyan leader Muammar Gaddafi - on charges of harming state security resumed Thursday in the western city of Zintan, dpa reported.
Following a short session, the court postponed the hearing until February 20 in response to a request from the younger Gaddafi's defence lawyer after other key defendants did not appear, reported Libya's state news agency.
The trial, which began in January, relates to an alleged attempt by Gaddafi's son to escape from Libyan authorities with the assistance of a team from the International Criminal Court (ICC).
In June 2012, Libya had detained an ICC delegation on suspicion of smuggling documents and spy gadgets to the younger Gaddafi while visiting him in prison. The ICC team members were later released after a protest from the court.
Gaddafi's son faces a separate trial for his role in attempts to crush an armed revolt that toppled his father's regime in 2011.
The younger Gaddafi has been held in Zintan - a small town south-west of Tripoli - since November 2011, when insurgents arrested him almost a month after his father was captured and killed.
Libya has resisted pressure from The Hague-based ICC to hand over Gaddafi's son to be tried for crimes against humanity during the uprising.
