A Tunisian court has sentenced the former head of a banned Islamist party to one year in prison for resuming contact with the group, only weeks after his release from a long jail term. A government official said Sadok Chourou was convicted Saturday of "maintaining an illegal association" after he argued in favor of legalizing the banned Ennahdha Islamist party in interviews with satellite television channel al Hiwar and spoke to other members of the group. Chourou was one of 21 party members pardoned and released in November. In 1992, more than 1,000 party members were sentenced to prison on charges they had plotted to topple the regime. His lawyer, Samir Ben Amor, said Chourou was considering whether to appeal.
