Tunisia's Ennahda movement announced in a statement Thursday evening the arrest of former president Sadiq Chourou. He spent 20 years in the prisons of the regime of the late President Zine El Abidine Ben Ali, most of them in solitary confinement.

A few days ago, a Tunisian court sentenced En Nahda leader Rached Ghannouchi to one year in prison and a fine. The Tunisian authorities have carried out a campaign of arrests that included leaders and activists in the opposition.
