A massive police operation targeting the notorious Red Command gang in Rio de Janeiro’s northern suburbs has resulted in at least 64 fatalities, marking the deadliest raid in the Brazilian state’s history. The operation, codenamed ‘Containment,’ took place in the Alemão and Penha districts, where fierce clashes erupted as approximately 2,500 security personnel moved in on Tuesday morning. The Red Command retaliated with gunfire, burning barricades, and deploying drone-dropped bombs, according to officials. Among the dead were four police officers, while over 80 individuals were arrested. State Governor Cláudio Castro confirmed that at least 50 of the deceased were identified by police as suspected criminals. The operation also left dozens injured, including civilians caught in the crossfire. The UN Human Rights Office expressed horror at the violence, calling for prompt and effective investigations. The targeted area, a cluster of favelas near Rio’s airport, is considered the stronghold of one of Brazil’s most powerful organized crime groups. Locals have described the aftermath as resembling a ‘war zone,’ with roads remaining closed throughout the region. Authorities seized more than 200kg of drugs and dozens of firearms during the raid, which followed a year-long investigation. The Red Command has been expanding its influence across Rio, intensifying drug trafficking and control over hillside favelas. This operation is part of a broader trend of large-scale police actions in Brazil ahead of major international events, such as the upcoming COP30 climate summit in November.
