The U.S. government is refusing to cooperate with Argentina's attempts to have a suspect connected to the 1994 bombing of the AMIA Jewish Community Center brought back to Buenos Aires. Antonio Horacio Stiuso, former chief of Argentina's intelligence agency and who was closely linked to U.S. intelligence and deceased prosecutor Alberto Nisman, flew to Miami eight months ago and despite a formal request, U.S. authorities have not informed Argentine officials of his whereabouts. Leonel Poblete reports from Buenos Aires. teleSUR
