RIO DE JANEIRO—At least 64 people died on Tuesday in Rio de Janeiro’s most deadly police operation ever, which targeted a major gang days before the city hosts global events related to the United Nations climate summit known as COP30.
Police have often conducted large-scale operations against criminal groups ahead of major events in Rio, which hosted the 2016 Olympics, the 2024 G20 summit and the BRICS summit in July.
