December 22, 1997, in a church in the town of Acteal in the state of Chiapas, Mexico, a group of ninety paramilitaries forcibly entered a church, attacking those present and killing sixteen children, twenty women and six men.
Although efforts were made because these events did not come to light, soon the news spread and provoked commotion inside and outside of Mexico, much more when it was associated with the aggressors with paramilitary groups sponsored by the Mexican government to fight the then active EZLN.
The case was investigated by the Inter-American Court of Human Rights, and although the Mexican government denied involvement in the events, it was soon discovered that the aggressors had been commanded by members of the Secretariat of Public Security, who received a conviction of just three years in jail.
The government of Mexico said that everything had been a conflict between communities, imprisoning several Indians as responsible for the massacre. Nowadays, there are still demands against the then president, Ernesto Zedillo, and the Acteal massacre is remembered as one of the most infamous impunity acts of state terrorism in Mexico.
