There has been a massive circulation of messages in the social networks in Mexico in support of the 43 disappeared students from the Teachers Training College in Ayotzinapa. Through these outlets, demonstrations and other other activities -including academic and artistic events- have been publicized to support demands that the Mexican government return the students alive. For example, on Friday a march will be held in Mexico City and the social networks are already innundated with messages promoting the demonstration. teleSUR
