Mexico City, November 21 (teleSUR-RHC)-- People from all over Mexico arrived Thursday in the capital city's main square to demand justice for the missing 43 students, as well as for all those who have gone missing or been murdered.

The biggest marches yet to demand justice in the case of Ayotzinapa coincided with the anniversary of the start of the Mexican Revolution 104 years ago.

Protests have been held around the world to call for the recovery of the 43 missing students in Mexico. Students at the University of Nottingham held a silent march on campus, dressed in black and holding banners with different messages under the refrain: “It’s not only 43.” One of the banners read: "It’s not only 43. It’s the 22,322 missing people since 2006."

In Germany, students gathered to support the Mexican demands for justice. Students of the University of Hong Kong also joined the protests. And thousands of protesters gathered in Barcelona, Spain under the motto: “Peña, understand the people do not want you.” Also in Spain, demonstrators gathered in Madrid to demand that Mexican President Peña Nieto step down.

Students also demonstrated in London, New York City, Amsterdam, Melbourne, Australia and in New Delhi, India, in solidarity with Ayotzinapa.

In Latin America, student-led demonstrations demanding justice for the missing Mexican students were held in many cities, including La Paz, Bolivia, San Salvador, El Salvador, in Venezuela and in Santiago de Chile.
