News - Middle East: Brazilian President Luiz Inacio Lula da Silva vows to purge the country's police force and the army of US-backed former president Jair Bolsonaro's sympathizers after the security forces refused to respond properly to destructive riots in the capital by Bolsonaro's supporters.

Lula pledged to carry out the purge on Thursday, less than a week after thousands of the former far-right head of state's supporters forced their way into the country's Congress, Supreme Court, and the presidential palace in the absence of much resistance on the part of the security forces.
