Supporters of former Brazilian President Jair Bolsonaro who refuse to accept his election defeat stormed the presidential palace after the inauguration of his leftist rival on Sunday.
Thousands of demonstrators bypassed security barricades, climbed on roofs, smashed windows and invaded the National Congress, the Palácio do Planalto (Presidential Palace), and the Supreme Court - which were believed to be largely vacant over the weekend.
Footage from the scene showed protesters draped in Brazil's flag ransacking new President Luiz Inacio Lula da Silva's personal office and hauling out personal items, including his sofa.
