A protester shouts slogans during the so-called "Jornada Nacional de Luta Pelas Vidas Negras" (National Day of Struggle for Black Lives) calling for an end to police violence against Brazilian black communities, in downtown Rio de Janeiro, Brazil on August 24, 2023. The act, organized by more than 250 Brazilian Black Movements, was called due to recent episodes of police violence and murders of black people in Brazil, including a 13- year old shot dead in an operation in Cidade de Deus shantytown earlier this month.
