The 73-year-old has appealed his conviction 11 times since becoming eligible for release in 1999. The court said the communist activist would be released on December 6 on the condition that he leaves France and does not return, French anti-terror prosecutors said in a statement to AFP.

The prosecutors said they would appeal the court's decision, leaving the timing of Abdallah’s release uncertain.

The Lebanese activist, born to a Christian family in the northern village of Koubayat, has long maintained that he was not a "criminal" but "a fighter" who battled for the rights of Palestinians.
