At least 64 Killed in Rio's Largest Law Enforcement Operation on Gangs

At least 64 people died in a law enforcement action cracking down on the organized crime group in the Brazilian city's northern districts - the biggest and most lethal operation in the Brazilian state's records.

Four law enforcement personnel lost their lives during the security mission in the communities of Alemão and Penha, government representatives reported. In excess of 80 individuals were arrested.

Fierce clashes broke out when around 2,500 police forces initiated the operation on Tuesday morning. The Red Command responded with armed resistance, burning barricades and dropping bombs from drones, officials confirmed.

The International human rights organization said it was "horrified" by the security action, urging "swift and comprehensive examinations".

State officials stated at least 50 of those killed were "identified by authorities as alleged offenders".

Local Reaction

Residents have described the elevated neighborhood - home to about 300,000 individuals - to a "war zone" since the raid started.

Transport routes stay blocked throughout the region.

Criminal Expansion

The criminal network has been increasing their control throughout the region, expanding narcotics distribution networks and power in the informal settlements.

Rio's police stated over 200kg (441lb) of drugs were seized in the operation, along with multiple guns.

Operation Background
