An opposition student protester gestures after injuring his left eye during a march toward the electoral commission, as he sits on the ground against the wall of a kiosk covered by a pro-Hugo Chavez sign in downtown Caracas, Venezuela, Thursday, March 21, 2013. Student protesters marching to protest against what they perceive as bias by Venezuela's electoral council clashed on Thursday with supporters of the late President Hugo Chavez. Police attempted to separate the rival groups, but scuffles broke out, prompting security forces to fire tear gas canisters and shoot plastic bullets at the Chavistas. Venezuela will hold a presidential election on April 14 to replace Chavez. (AP Photo/Ariana Cubillos), APTOPIX
