A high-ranking member of the FARC revealed to the Associated Press, Thursday, Sept. 13, 2012, that Calarca is one of five main negotiators representing the rebel group in peace talks with the Colombian government, on condition of anonymity because he was not authorized to speak publicly ahead of a formal announcement. The talks start in Norway next month. (AP Photo/Ramon Espinosa)
