In a statement released Thursday, the international rights group condemned the verdict and demanded the immediate release of Ali Hussain Sibat, former host of a popular call-in show that aired on Sheherazade, a Beirut based satellite TV channel.
According to his lawyer, Sibat, who is 48 and has five children, would predict the future on his show and give out advice to his audience.
The attorney, May El Khansa, who is in Lebanon, tells CNN her client was arrested by Saudi Arabia's religious police (known as the Mutawa'een) and charged with sorcery while visiting the country in May 2008. Sibat was in Saudi Arabia to perform the Islamic religious pilgrimage known as Umra.
Sibat was then put on trial. In November 2009, a court in the Saudi city of Medina found Sibat guilty and sentenced him to death.
