Two Chicago-based organizations are asking an international human rights commission to examine the U.S. government’s treatment of thousands of unaccompanied minors who’ve entered this country from Mexico and Central America.Last week, a petition was filed with the Inter-American Commission on Human Rights on behalf of the National Immigrant Justice Center and the National Alliance of Latin American and Caribbean Communities. The commission is under the auspices of the Organization of American States, a regional group of which the U.S. and all the countries in the Americas are members. The Chicago groups are asking the commission to urge the U.S. to take precautions in how it treats the children and their families in this country. They also request that the commission order the U.S. to stop deporting the children and their families without due consideration of their rights to protection and asylum, said Susan Gzesh, the executive director of the Pozen Family Center of Human Rights at the University of Chicago and one of the lawyers who helped write the petition. Since October 2013, close to 60,000 unaccompanied children from El Salvador, Guatemala, Honduras, and Mexico have been apprehended by U.S. authorities at or near the U.S.-Mexico border, according to the Pew Research Center.The children are fleeing kidnapping, mutilation, rape and murder in their countries.
