On 2 October 1968, thousands of students protested in Mexico City, 10 days before the Olympics. The students wanted the government to free political prisoners and respect their right to protest. More than 4,000 activists came to the Plaza de las Tres Culturas in the capital's Tlatelolco district that evening. It resulted in Mexican soldiers opening fire on the protesters. The death toll has never been confirmed, a government report from the time put it at 26, while student leaders estimated it at more than 100. In 2011, one of the young protesters, David Huerta, spoke to Julian Miglierini. Eye-witness accounts brought to life by archive. Witness History is for those fascinated by the past.
