Nicaragua's Ortega government detained two presidential hopefuls yesterday -- Félix Maradiaga and Juan Sebastián Chamorro -- continuing a roundup of the most significant opposition leaders ahead of a presidential election in November. Félix Maradiaga, a Harvard-educated academic and political activist, was detained after being summoned for questioning by the federal prosecutor’s office. Authorities are investigating him for allegedly inciting foreign interference in Nicaragua’s affairs, “asking for military intervention and organizing terrorist acts with financing from foreign powers” -- charges Maradiaga dismissed as trumped up and politically motivated.
