PARIS - French prisoners are often overwhelmingly Muslim, with many inmates converting to Islam while behind bars, an expert told a French newspaper yesterday.

Muslims often account for over half the population of many French prisons, while penitentiaries close to rough suburbs could have up to 80 percent Muslim inmates, Fahrad Khosrokhavar, a French author and academic, was quoted as saying in Le Figaro newspaper yesterday.
