Copyright Demotix Tens of thousands of people marched from the presidential palace to Mexico City's main plaza to demand the safe return of 43 missing education students and protest the regional government's role in their disappearance along with the president's inefficient response to the crime. Organizers said 120,000 people participated in the Global Day of Action for Ayotzinapa in the city, organized by various Mexican student groups, while police counted 60,000. Protesters’ cries for justice reached every corner of Mexico and the world; news site Revolucion 3.0 described the demonstration as possibly “the largest condemnation march in history” and shared an audiovisual gallery with minute-to-minute updates of the movement. The protests occurred a day after José Luis Abarca, former mayor of Iguala and his wife María de los Ángeles Pineda, were arrested by federal forces in Mexico City in the early hours of Tuesday, November 4, 2014. Both have been identified by the government and the media as the alleged masterminds behind the initial attack against the students, which left six dead, and the subsequent disappearance of the 43 in Ayotzinapa. Social media users shared messages in support of the march and images from the scene: Al grito de “Estado farsante que matas Estudiantes’ #AccionGlobalporAyotzinapa#43×43pic.twitter.com/CseN04mfcB — Ari Telch (@aritelch) November 5, 2014 With the cry of “deceitful state that kills students” Fue el estado, fue el gobierno, fuimos todos, ¡NO más impunidad en #México! #AccionglobalporAyotzinapa — Rosa Mondragón (@rosemondragon) November 6, 2014 It was the state, it was the government, it was all of them, no more impunity in Mexico!
