Police have identified the man who killed himself in a blast outside Brazil's Supreme Court on Wednesday night as a former city council candidate from ex-President Jair Bolsonaro's right-wing party with a history of heated political rhetoric online.

Authorities in Brazil on Thursday were searching for the motive of a man who apparently tried to bomb the Supreme Court, killing himself in the process.While a motive has not yet been determined, the bombing immediately evoked memories of last year's attack on Congress,

The authorities were treating the blasts in Brasília, the capital, as the work of a lone bomber, who was believed to have been the person killed.
