Former Chile's president Sebastian Pinera (R) walks among national guards outside the military prison of Ramo Verde at the outskirts of Caracas January 25, 2015. Two former Latin American presidents were blocked on Sunday from visiting jailed Venezuelan opposition leader Leopoldo Lopez, who was arrested last year after leading protests against the government of President Nicolas Maduro. Former presidents Sebastian Pinera of Chile and Andres Pastrana of Colombia, both conservatives who were U.S. allies, were denied access to the prison where Lopez is being held.
