SAO PAULO (AP) — Brazil's president says he wants a public ministry to coordinate security operations in the entire country.

President Michel Temer spoke briefly Saturday in Rio de Janeiro after talking to local authorities about the implementation of a decree that has placed the military in charge of the state's security operations amid a spike in violent crime.

"We must join forces to combat crime," he said, but gave no details about the ministry he plans to create within the next few weeks.

Temer had met with Rio state Gov. Luiz Fernando Pezao and Army Gen. Walter Souza Braga Netto, who was appointed to lead the security intervention.

The decree, which was already signed by Temer, is expected to be approved by Congress next week.

The Brazilian arm of Amnesty International said Saturday that the decision to intervene in Rio de Janeiro's local police "reinforces mistakes that have already been made in the past." It also said that none of the military's previous actions had managed to reduce homicides.
