According to CNN, Interim Senate President Veneziano Vital do Rogo said another video from the capital city of Brasilia showed enormous crowds making their way up a ramp to the legislative building and into the Green Room, which is outside the chamber of the lower House.

Other videos from local news outlet showed showed Bolsonaro suporters entering the Supreme Court and the presidential palace and the arrivals of anti-riot police and the Brazilian Armed Forces.

Protesters inside had erected barriers out of furniture to keep police out. When demonstrators tried to light the carpet on fire in the Congress building, the sprinkler system was triggered, flooding the floor.

Another footage also shows demonstrators trashing artwork and stealing presents from foreign delegations inside the facility.

Luiz Inacio Lula da Silva Vows to Punish Everyone Involved in Brazil Attack

In a fiery address on Sunday, Luiz Inacio Lula da Silva blamed Jair Bolsonaro for the disruption and said "anyone involved would be punished" even though he was not in Brasilia then.

Lula authorized a federal intervention in the capital, placing policing under the national government's jurisdiction, and labeled those responsible for the assaults "vandals, neo-fascists, and fanatics."

Mobs were met with minimal resistance as they advanced towards the three branches of government in Brasilia, where the military police were noticeably absent.

Lula said that law enforcement agencies in the nation's capital showed "incompetence, bad faith, or malice" and vowed for a speedy response.

On Sunday, Lula plans to return to the nation's capital and see the three damaged structures. According to Federal District Governor Ibaneis Rocha, at least 400 people have been arrested. 

Dozens could be seen on TV lying shackled on the ground while police stood over them, The Guardian reported.

Some hours before Lula's response, a Bolsonaro-supporting crowd had stormed from the army headquarters in Brasilia towards the Three Powers Plaza, home to the Brazilian supreme court, the presidential palace, and the legislature.

Police lines were broken as the militants, many of whom were wearing the yellow and green colors of Brazil flag that has become a symbol of Jair Bolsonaro's far-right movement, rushed up the ramp into the parliamentary building.

World Leaders React to Brazil Attack

Leaders in Latin America have reacted against the violence. The president of Chile, Gabriel Boric, has pledged his country's "full support" in the face of this shameful and terrible attack on democracy in Brazil.

"Fascism [had] decided to stage a coup," said Colombian President Gustavo Petro.

Mexican Foreign Minister Marcelo Ebrard noted that his country "fully supports" the administration of Luiz Inacio Lula da Silva who was elected by popular will.

Josep Borrell, the EU's top diplomat, also condemned the incident as "appalling" and expressed confidence that Brazilian democracy will win over violence and extremism.

French President Emmanuel Macron has also shown his unfailing support for Lula and said the "will of the Brazilian people and the democratic institutions must be respected."

U.S. President Joe Biden tweeted: "I condemn the assault on democracy and on the peaceful transfer of power in Brazil. Brazil's democratic institutions have our full support, and the will of the Brazilian people must not be undermined."

Lula is presently engaged in official business in the state of So Paulo, BBC reported. He said the country was in "terrible ruins" during his inaugural address and promised to restore it.
