PARIS: Politicians, writers and activists have called for the release of French-Algerian writer Boualem Sansal, whose arrest in Algeria is seen as the latest instance of the stifling of creative expression in the military-dominated North African country. The 75-year-old author, who is an outspoken critic of Islamism and the Algerian regime, has not been heard from by friends, family or his French publisher since leaving Paris for Algiers earlier this month. He has not been seen near his home in his small town, Boumerdes, his neighbors told The Associated Press.
