Riots in Chile's capital Santiago escalate into open battles, with attacks reported at nearly all of the city's 164 Metro stations. President Sebastián Piñera later announces a 15-day state of emergency in the capital.

A series of massive demonstrations and severe riots, known in Chile as the Social Outburst, originated in Santiago and took place in all regions of Chile, with greater effect in the regional capitals. The protests mainly occurred between October 2019 and March 2020, in response to a rise in the Santiago Metro's subway fare, a probity crisis, cost of living, university graduate unemployment, privatisation, and inequality prevalent in the country.
