In a tragic turn of events, at least 132 individuals, including four police officers, lost their lives on Tuesday following a massive police operation in Rio de Janeiro, Brazil, as reported by various media outlets.

The operation, conducted in the city’s favelas—areas notorious for their struggles with organized crime—marked a grim milestone as the deadliest police raid in Rio’s history, according to the BBC. Authorities aimed to dismantle the drug gangs dominating extensive sections of the city, specifically targeting the influential Comando Vermelho, or “Red Command” group.

The death toll was confirmed by the local public defender’s office, though Rio’s state Governor, Cláudio Castro, highlighted that forensic investigations were still ongoing. He mentioned that the official figure he received was 58 fatalities, though he noted this number was “certain to change.”

Governor Castro clarified, “To be quite honest, the conflict did not occur in populated areas—it was in the woods. No one was casually wandering through the woods during such a conflict, which is why we can categorize them easily.”

Authorities disclosed that gang members allegedly resorted to using drones to deploy explosives against police officers during the operation.

“This is how the Rio police are treated by criminals: with bombs dropped by drones. This is the scale of the challenge we face. This is not ordinary crime, but narco-terrorism,” Castro said.

Brazilian President Luiz Inácio Lula da Silva expressed shock over the killings and said he was surprised the federal government had not been informed about the raid beforehand.

On X, formerly Twitter, Castro said the raid had been planned for more than two months following a year-long investigation and that “the scenario encountered was the one that had been anticipated.”

He also paid tribute to the four officers killed during the operation.

“Marcus Vinícius Cardoso de Carvalho, commissioner of the 53rd Police Station; Rodrigo Velloso Cabral, from the 39th Police Station; and Cleiton Serafim Gonçalves and Heber Carvalho da Fonseca, both sergeants of BOPE, gave their lives fulfilling the duty to protect the Fluminense population,” the governor wrote.

On Wednesday, Castro’s office said 113 people had been arrested, 10 teenagers were detained and authorities seized 91 rifles, 29 pistols, 14 explosive devices and one ton of cocaine.

The deadly raid has renewed debate in Brazil over police tactics, human rights, and the government’s ongoing struggle to control powerful gangs entrenched in Rio’s impoverished communities.
