Three new clandestine mass graves were discovered in the village of Carrizalillo in the southwestern Mexican state of Guerrero, where the 43 Ayotzinapa students were forcibly disappeared in September 2015. Area residents attribute the mass graves to killings by the Guerreros Unidos organized crime gang, which has been linked to the disappearance of the Ayotzinapa students. The number of bodies contained in the graves has not yet been disclosed. Forensic teams are at work exhuming the bodies. Clayton Conn reports from Mexico City. teleSUR
