In Brazil, tens of thousands of people filled the streets of Rio de Janeiro Thursday to protest the apparent assassination of 38-year-old city councilmember and human rights activist Marielle Franco. Franco died along with her driver Wednesday night, after a pair of gunmen riddled her car with bullets. Franco was a fierce critic of police killings in Brazil’s impoverished favela neighborhoods. The night before her death, Franco wrote on Twitter, “How many more must die for this war to end?” In January alone, government figures show police killed 154 people in Rio state. Franco’s murder came a month after President Michel Temer ordered Brazil’s military to assume control of police duties in Rio.
