MEXICO MASSACRE PICTURES

University student Florencio Lopez Osuna, badly beaten, poses for an unknown photographer inside an apartment building in Tlatelolco, Mexico City, in this Oct. 2, 1968 photo. A Mexican magazine published photos, including the one shown, showing that paramilitary forces hired to provide security during the 1968 Olympic games apparently participated in a massacre of student protesters _ something past Mexican governments have denied.
