On this day, 22 December 1997, 45 indigenous people who were supporters of the Zapatista rebel movement in Chiapas, Mexico were massacred by paramilitaries as they attended a pacifist prayer meeting.
Government troops nearby failed to intervene to prevent the attack, instead they tried to cover up the killings, cleaning the blood off the church where the Catholics, and some of their unborn children were killed as pregnant women were shot and stabbed in the stomach. https://www.facebook.com/workingclasshistory/photos/a.296224173896073/1300188730166274/?type=3
