Venezuela's opposition leader, María Corina Machado, has called for mass protests across the nation on July 3 to denounce the disputed reelection of President Nicolas Maduro. Machado, who had been in hiding for several days, emerged on Saturday to lead a significant rally in Caracas. Tens of thousands of opposition protesters gathered in the capital, where Machado addressed the crowd, calling for Maduro to step down amid claims of election rigging. The protests are set to occur in every city in Venezuela, with Machado urging citizens to participate. Maduro's supporters have also been mobilized for competing rallies. AFP reported on Machado's emergence and participation in the rally.
