What happened: Thousands, many from Generation Z and the local "Sombrero Movement," marched on the Zócalo in Mexico City and clashed with police outside the National Palace.
Casualties and arrests: Authorities reported more than 100 people injured — including around 20 protesters and 100 police officers (40 hospitalized) — and 20 arrests.
Context: The protest was fuelled by outrage over the assassination of Mayor Carlos Manzo and broader concerns about violent crime; investigations into assaults, including one on a La Jornada journalist, are under way.
