Protesters in Mexico City drove a pickup truck through the door of the presidential palace, where President Andres Manuel Lopez Obrador was holding a press conference. Police responded by using tear gas. The protesters were demanding justice for the 2014 disappearance of 43 Mexican students, which a commission later labeled as “a crime of the state.” The students were traveling back from a protest when they were attacked by municipal police. Three students were killed, and their deaths remain contentious, with conflicting accounts of the events leading up to the attack. The students were apparently confronted by municipal police, who opened fire on the buses they were travelling in. The officers maintain they did so because the buses had been hijacked, while the surviving students say the drivers had agreed to give them a lift. President Lopez Obrador assured that the damaged door would be fixed, and he promised a meeting between the protesters and members of his government to address their concerns.
