Pro-Bolsonaro rioters storm Brazil's Congress, Supreme Court and presidential palace

Supporters of former Brazilian president Jair Bolsonaro who refuse to accept his electoral defeat stormed Congress, the Supreme Court and presidential palace in the capital on Sunday, just a week after the inauguration of his leftist rival, President Luiz Inacio Lula da Silva.

Thousands of demonstrators bypassed security barricades, climbed on roofs, smashed windows and invaded all three buildings, which were believed to be largely vacant on the weekend. Some of the demonstrators called for a military intervention to either restore the far-right Bolsonaro to power or oust Lula from the presidency.

Hours went by before control of the buildings on Brasilia's vast Three Powers Square was reestablished, with hundreds of the participants arrested.

In a news conference from Sao Paulo state, Lula accused Bolsonaro of encouraging the uprising by those he termed "fascist fanatics," and he read a freshly signed decree for the federal government to take control of security in the federal district.

"There is no precedent for what they did and these people need to be punished," Lula said.

TV channel Globo News showed protesters wearing the green and yellow colours of the national flag that also have come to symbolize the nation's conservative movement and were adopted by Bolsonaro's supporters.

The former president has repeatedly sparred with Supreme Court justices, and the room where they convene was trashed by the rioters. They sprayed fire hoses inside the Congress building and ransacked offices at the presidential palace. Windows were broken in all of the buildings.

Bolsonaro, who flew to Florida ahead of Lula's inauguration, repudiated the president's accusation late Sunday. He wrote on Twitter that peaceful protest is part of democracy but vandalism and invasion of public buildings are "exceptions to the rule."

Bolsonaro's supporters have been protesting against Lula's electoral win since Oct. 30, blocking roads, setting vehicles on fire and gathering outside military buildings, asking the armed forces to intervene. The head of Brazil's electoral authority rejected the request from Bolsonaro and his political party to nullify ballots cast on most electronic voting machines.

Police fired tear gas in their efforts to recover the buildings, and were shown on television in the late afternoon marching protesters down a ramp from the presidential palace with their hands secured behind their backs. By early evening, with authorities' control of the buildings restored, Justice Minister Flavio Dino said in a news conference that roughly 200 people had been arrested and officers were firing more tear gas to drive away lingering protesters.

But with the damage already done, many in Brazil were questioning how the police had ignored abundant warnings, were unprepared or were somehow complicit.

Lula said at his news conference there was "incompetence or bad faith" on the part of police, and that they had been likewise complacent when Bolsonaro supporters rioted in the capital weeks ago. He promised those officers would be punished and expelled from the corps.

Earlier videos on social media showed a limited presence of the capital's military police; one showed officers standing by as people flooded into Congress, with one using his phone to record images. The capital's security secretariat didn't respond to a request from The Associated Press for comment about the relative absence of the police.

"Brazilian authorities had two years to learn the lessons from the Capitol invasion and to prepare themselves for something similar in Brazil," said Mauricio Santoro, political science professor at the State University of Rio de Janeiro. "Local security forces in Brasilia failed in a systematic way to prevent and to respond to extremist actions in the city. And the new federal authorities, such as the ministers of justice and of defence, were not able to act in a decisive way."
