Brazil’s Defense Minister Aldo Rebelo downplayed on Wednesday risks of massive protests during the Olympic Games in Rio de Janeiro, despite the country’s economy and political crisis and a mushrooming scandal at state-run oil giant Petrobras.

Rebelo told a news conference in Brasilia that the expected 85,000 security agents, including 38,000 members of the armed forces, will be enough to guarantee safety during the games from Aug. 5-21.

The minister also said that violent protests, like those during the 2013 Confederations Cup, are not likely, but “have to be confronted and repressed if they happen”.

“I don’t think we will see what happened in 2013. During the World Cup that (tension) was much cooled down,” Rebelo said. “The Olympics will be in a much calmer atmosphere in comparison with 2013.” Rebelo was Brazil’s Sports Minister in the last edition of the Confederations Cup.

Many Brazilians are expected to take to the streets again this weekend, with different groups either demonstrating their opposition to _ or support for _ President Dilma Rousseff, who faces impeachment proceedings. Some groups have promised to protest during the Games, especially movements of displaced by Olympic constructions.

Brazil’s Defense Minister said that members of the Armed Forces will only act when local police can’t.

He also said Brazil is working with the United States, the United Kingdom and Russia, among others, to stop terrorist threats.

“(The effort) is not because of Paris (terrorist attacks). Since the Olympics in Munich in 1972 that concern exists,” Rebelo said, in a reference the assassination of Israeli Olympic athletes by terrorists. “There was an attack in Atlanta-1996 too. There are many examples in the past.”

Rio’s top state security official, Jose Mariano Beltrame, has repeatedly said that preventing terrorism has “always been the No. 1 priority” in Olympic planning, even though Brazil does not have a history of attacks. The more visible problem in Rio is endemic street crime.

Brazil is expected to spend about $ 190 million dollars in security operations (more than 700 million reals). Rebelo said that the Armed Forces contingent will be reduced in at least 18,000 members for the Paralympic Games from Sep. 7-18.

In November a government watchdog said that “flaws” in Brazil’s border security are also a “big concern” for Rio 2016. According to auditor Augusto Nardes, Brazil’s police and military need better ways to control the country’s 17,000 kilometer-long (10,500-mile) border, which touches 10 countries and runs through remote areas of the Amazon jungle.
