“Eight Brazilians arrested before the Rio Olympics for belonging to a loosely organized group that supported Islamic State and discussed attacking the games were charged on Friday under Brazil’s anti-terrorism law. The men, who were loosely connected by the internet, were arrested in July two weeks before the Olympics opened in Rio de Janeiro. Police working on an intelligence tip from the FBI traced them through email exchanges about the purchase of an automatic weapon and discussion of plans for a possible attack on the Games.”
