The Inter-American Commission on Human Rights (IACHR) will be holding its 156th session this week in Washington. Discussion will center on Mexico's human rights crisis, and more specifically the forced disappearance of the 43 Ayotzinapa students. A delegation of the students' family members and Mexican human rights organizations will be present for the meeting. In four hearings the IACHR will discuss the country's myriad human rights violations and widespread impunity with Mexican authorities. Clayton Conn reports from Mexico City. teleSUR
