Honduras's leftist presidential candidate Xiomara Castro will call massive street protests Saturday over what her campaign termed the theft of the country's presidential vote. "On Saturday, we are going to summon people to protest. The Libre (Party) and Xiomara (Castro) have been robbed of their victory, and we are going to show it," her husband, ousted ex-president Manuel Zelaya, told Radio and TV Globo in an interview.
