In Mexico, tens of thousands of people marched through Mexico City to mark the fortieth anniversary of the 1968 Tlatelolco massacre of student protesters. Human rights groups estimate up to 300 people were killed when government forces opened fire on students gathered in Tlatelolco Plaza. Marcelino Perello, a university professor who helped organize the protests in 1968, said their legacy should inspire movements for social justice today.

Marcelino Perello: “I think that the 1968 legacy is yet to become a reality. We are still suffering from a hangover. We are living through a dark moment in history, but the same story will again lead us to sweeter times, to the resurrection of the popular struggle for freedom and justice.”

The Mexican government has been accused of failing to investigate the massacre properly. Former government officials have been accused of ordering police to open fire. Earlier this week, Amnesty International asked the Mexican government to launch an extensive probe.
