Massive March to Zócalo — 50,000 Protesters

An estimated 50,000–100,000 students and supporters march from Ciudad Universitaria to the Zócalo, Mexico City's central plaza, in the largest demonstration of the movement. Some students occupy the Zócalo overnight. The government orders the army to clear the plaza at 1:00 AM, resulting in violent confrontations. The event signals the government's hardening stance.
