In Mexico, authorities are bringing criminal charges against military soldiers for the first time in the ongoing investigation into the 2014 disappearance and likely massacre of 43 students from a teachers’ college in Ayotzinapa, Guerrero. Mexican authorities announced Tuesday they have issued at least 25 arrest warrants against suspects believed to be the “material and intellectual authors of the disappearance,” including a former head of the federal police. Families of the disappeared students have long maintained the military was involved in the mass abduction.
