Bolsonaro supporters storm the National Congress in Brasilia, Brazil, 08 January 2023.
Supporters of Brazilian far-right ex-President Jair Bolsonaro have stormed Congress and the Supreme Court and surrounded the presidential palace.
The dramatic scenes come a week after left-wing veteran Luiz Inácio Lula da Silva's inauguration.
Supporters of Mr Bolsonaro - who refuse to accept that he lost the election - broke through police barriers in the capital, Brasília.
Police used tear gas but failed to repel the demonstrators.
Protesters have smashed windows, while others reached the Senate chamber, where they jumped on to seats and used benches as slides.
It is unclear if they are still in the building.
Many are drawing comparisons with the storming of the US Capitol on 6 January 2021 by supporters of Donald Trump, an ally of Mr Bolsonaro.
Mr Bolsonaro's supporters are calling for military intervention and the resignation of Mr da Silva - better known as Lula - who defeated his far-right rival in October's election.
Many of them created camps in cities across Brazil, some of them outside the military barracks. That's because his most ardent supporters want the military to intervene and make good elections that they say were stolen.
It looked like their movement had been curbed by Lula's inauguration - the camps in Brasilia had been dismantled and there was no disruption on the day he was sworn in.
But Sunday's scenes show that those predictions were premature.
Lula is currently on an official trip in São Paulo state.
In his inauguration speech, he vowed to rebuild a country in "terrible ruins".
He decried the policies of his predecessor, who went to the US to avoid the handover ceremony.
