Mexico City, November 20 (teleSUR-RHC)-- Tens of thousands of Mexicans are expected to join three marches to demand justice for the 43 missing Ayotzinapa students in the capital’s main square.

In spite of threats from the president, who said he will use force to disperse “violent” demonstrations that “seem to seek to destabilize his administration,” the protesters will demand justice in the Ayotzinapa case.

This time, a total of three marches will unite in the capital’s main square, the Zocalo, in front of the presidential palace. A national strike has also been called for today.

The first march is scheduled to start at the Angel of Independence monument, located on Mexico City’s main avenue, Paseo de la Reforma, where anyone not affiliated with the groups on the other two marches will gather before marching to the Zocalo.

Meanwhile, unions and farmers, from all over the country, will gather at the Revolution Monument before starting their march.

Also, students and teachers, arguably the most active sector of society with regard to Ayotzinapa protests, will gather at Tlatelolco square before marching down Eje Central avenue towards the focal point in the demonstration: President Peña Nieto’s offices.

The date of the mass rally was chosen deliberately; November 20th marks the 104th anniversary of the Mexican Revolution. In its annual celebrations, the president presides over a Zocalo square filled with parades of athletes and soldiers. This year, however, federal authorities have announced that the ceremonies have been canceled.
