The Moroccan Interior Ministry arrested 56 suspected terrorists in six cities on August 7, 2006. The suspects, believed to be members of the Jammaat Ansar El Mehditerrorist organization, include soldiers and wives of two pilots for Royal Air Maroc, the Moroccan state airline. Explosives, laboratory materials and propaganda leaflets were seized by police. In 2003 suicide bombings killed 45 people in Casablanca. Human rights activists accuse the Moroccan government of detaining innocent people and using torture. Commenting on the arrests on September 1, Minister Benmoussa said in a statement, "The members of this group were planning terrorist attacks targeting tourist sites, strategic government facilities and foreign holdings, and assassinations of prominent figures for political or moral reasons."
