Turmoil in Venezuela and the progress in the peace talks for the civil war in Colombia are the twin themes this week on Latin Pulse. The first half of the program analyzes the politics surrounding the arrest of Mayor Antonio Ledezma of Caracas and how that arrest has drawn international reaction. The second half of the program tracks the ongoing talks attempting to end the 51-year-old war in Colombia. The news segment of the program covers the latest in the case of Alberto Nisman in Argentina and how a judge has set aside an indictment against the country's president.
