Tens of thousands of protesters are expected today in Mexico City what promises to be a massive demonstration in solidarity with the 43 missing Ayotzinapa Teachers Training College students. Three informational caravans staffed by family members of the 43 and fellow Ayotzinapa students that have been visiting towns and cities across Mexico are scheduled to arrive in the capital and head three simultaneous marches that will converge on the central city square. President Enrique Peña Nieto has threatened that if demonstrations turn violent force will be used. teleSUR
