Background on the Situation

In a recent police operation targeting the Comando Vermelho, a major criminal organization in Rio de Janeiro, over 119 people have lost their lives, including four police officers. This tragic event marks the deadliest operation in Brazil’s history, surpassing the 1992 Carandiru massacre.

Operation Objectives and Targets

The operation, known as “Contención,” aimed to weaken the Comando Vermelho, which has become the most extensive criminal group in Rio and expanded significantly in recent years. The police targeted the favelas of Alemao and Penha, believed to be central bases for the organization.

While Comando Vermelho has surpassed milicias in territorial reach, the dominance of criminal organizations in Rio remains a subject of debate among experts.

Casualties and Arrests

According to the state government, 119 people have died, though the Public Defender’s Office reported 132 fatalities to AFP. Additionally, 113 individuals have been arrested, including ten adolescents, and 91 firearms were seized. The police also confiscated a “large amount of drugs,” though the specific quantity and type have not been disclosed.

This operation is the deadliest in Brazil’s history, exceeding the 1992 Carandiru massacre with 111 fatalities. In Rio, the second and third deadliest operations occurred in Jacarezinho and Vila Cruzeiro, resulting in 28 and 25 deaths, respectively, under the current governor Cláudio Castro.

Political Context

The operation was devised and executed by the Rio de Janeiro state government, led by Governor Castro, an ally of former far-right president Jair Bolsonaro. The federal government, under President Luiz Inácio Lula da Silva, was reportedly unaware of the operation.

Unanswered Questions

Identifying the Deceased and Arrested

The identities of those killed remain unknown, making it unclear if all were targeted suspects. Similarly, the identities of most arrested individuals have not been disclosed, hindering an assessment of the impact on Comando Vermelho’s structure.

Reports suggest that Thiago “Belao” do Nascimento Mendes, a lieutenant of “Doca” Alves de Andrade (alleged Comando Vermelho leader in the region), may have been captured. However, “Doca” managed to escape.

Local residents have accused the police of “executions,” and Brazil’s attorney general has demanded details from Governor Castro to determine if the police actions adhered to the law.

UN Secretary-General António Guterres has called for an “immediate” investigation into the events.
