Human rights groups from Mexico and Central America are traveling to the United States to submit their analysis of regional rights violations to the Inter American Commission on Human Rights (IACHR) at the end of this week. They are especially concerned about the situation of migrants and will present a plan for a transnational mechanism for pursuing justice in the cases of extortions, kidnappings and disappearances. The Mexican government is also expected to present a report on the Ayotzinapa case and on forced disappearances in general to the IACHR. Caravans of Ayotzinapa students and parents now criscrossing the United States are demanding that Mexico's federal government report all of the information to the IACHR.
