Abdullah was one of 12 opposition figures who signed a "Damascus Declaration" calling for democratic change in Syria. They were convicted to jail terms in October 2008.
Four of them have been released over the past week after having served their full terms.

He was also accused of "spoiling Syria's relations with another country" for an article he wrote from his prison cell criticising the supremacy of religious rule in Iran, a close ally of Syria.
