Yesterday in the Mexican state of Guerrero, a busload of students returning from a protest in solidarity with the Ayotinapa 43 (teaching college students who were kidnapped in late September by corrupt authorities in Iguala) was stopped by the army, who forced the students out of the bus, intimidated them, and told them to stop protesting, before photographing them and sending then back on their way. Also yesterday, parents of the 43 missing Ayotzinapa students recurred to the Organization of American States' Inter-American Commission on Human Rights, with whom they signed a contract. The OAS has pledged to help protect the families from danger, and to help continue the search for their children. teleSUR
