At least eight people died when police raided a drug-scarred Rio de Janeiro neighborhood on Monday, amid a sharp jump in police killing of suspected criminals in the state that underlines the tough new security measures favored by far-right President Jair Bolsonaro.

The raid began around 11 a.m., according to local media reports, and triggered a massive shootout between police and suspected gangsters. TV images showed a police helicopter hovering overhead as the gun battle emptied out local schools, with pupils fleeing through the streets.

In a statement, Rio's civil police said the operation was aimed at detaining Thomaz Jhayson Vieira Gomes, known as "3N," a suspected drug baron.
