Protesters are demanding Maduro publish voting data in an election they say he stole, and the authoritarian socialist has responded with force.

At least 16 people have been killed in clashes across the country since the vote Sunday, according to the rights group Foro Penal and a survey of hospitals. The dead include one soldier, the defense ministry said.

Jorge Rodríguez, president of the Maduro-controlled national assembly and brother of Maduro's vice president, blamed Machado and González for the violence and demanded their arrests. The government, he said, doesn't negotiate with "fascists."
