Brazil's former President Jair Bolsonaro condemned "pillaging and invasions of public buildings" on Sunday night, after hundreds of his supporters stormed Congress, the presidential palace and the Supreme Court, AFP reports.
Bolsonaro rejected what he called new President Luiz Inacio Lula da Silva's "baseless" accusations that he incited the invasion of the seat of power in Brasilia.
In a post on Twitter, the ex-president -- who left Brazil for Florida last month on the second-to-last day of his term -- also defended the right to "peaceful protests."
At least 150 supporters of Bolsonaro were arrested on Sunday after security forces in Brazil regained control of the Congress building, the Supreme Court and the Presidential Palace.
Protesters smashed windows, while others reached the Senate chamber, where they jumped on to seats and used benches as slides.
Footage on social media showed protesters pulling a policeman from his horse and attacking him outside the building, according to the BBC.
Da Silva said earlier on Sunday that the perpetrators will be found and punished, adding there was "no precedent in the history of our country" for the scenes seen at Congress and at the Supreme Court.
He called the violence the "acts of vandals and fascists".
Supporters of Bolsonaro have claimed the election was stolen. Hardcore supporters have even openly called for a military coup in order to put him back in charge, with some seeking to sow chaos through vandalism and violent attacks in hopes of triggering a military response.
Bolsonaro challenged the election in November, arguing votes from some machines should be "invalidated". However, the head of Brazil's electoral court rejected the complaint.
