Venezuela's Guaido starts domestic tour to stir support
Venezuela's self-proclaimed interim leader Juan Guaido began a tour of his country Saturday aimed at sparking a citizen's movement to pry President Nicolas Maduro from power. As Guaido, 35, kicked off his "operation freedom" in the northern city of Valencia, the pro-Maduro military staged the latest in a series of exercises. The drill focused on defending hydroelectric infrastructure from attack -- a reaction to a weeklong national blackout that Maduro blamed on US "sabotage" but experts said was more likely the result of years of neglect.
