Seif al-Islam, son of slain Libyan dictator Moamer Kadhafi, appeared in court Thursday in Zintan west of Tripoli on security charges in a trial that was adjourned until December, a lawyer said.

"Seif al-Islam Kadhafi appeared before the Zintan court that decided to adjourn the trial until December 12 to allow the attendance of other accused in the case," the lawyer who was present in court told AFP.

He was also due at a pre-trial hearing in the capital on Thursday on security charges related to the 2011 uprising that toppled his father, but there were doubts whether his ex-rebel captors in Zintan would allow this.
