Seif al-Islam, son of Libya's late dictator Moammar Gaddafi, appeared in court on Thursday charged with illegally trying to communicate with the outside world in June last year.

The man once assumed to be his father's heir appeared in good health at the hearing in the western town of Zintan.

The charges were leveled against Seif after the ICC team met him in Zintan and were themselves detained for nearly a month, triggering a diplomatic row with The Hague-based court. They were finally allowed to return home in July.

The judges decided to adjourn Thursday's trial until September 19 at the request of the defense team, who wanted access to the whole file on the case.

Only press reporters were admitted to the courtroom on Thursday, and Libyan national television was allowed to film the hearing.

Former Libyan President Moammar Gaddafi was ousted in 2011 uprising. Rebels arrested and killed him without facing trial.
