The wave of protests and riots in Brazil have prompted the Brazilian military police and army to set up barriers before the headquarters of the Brazilian armed forces in the capital, Brazilia, near a tent camp set up by supporters of former President Jair Bolsonaro, Brazilian media reported on Monday.

The camp was erected by Bolsonaro supporters a few weeks back, media reports have said. However, more than 100 buses carrying some 4,000 people from all over Brazil arrived at the site over the weekend.

Supporters of Bolsonaro broke into the Planalto presidential palace and Congress building on Sunday, in protest against leftist President Luis Inacio Lula da Silva who defeated far-right Bolsonaro in the presidential elections held on October 30.

Hundreds of protesters holding the Brazilian flag stormed the national congress and took the roofs waving the country's flags despite attempts by security officers to contain the unrest, an AFP photographer reported.

The Supreme Court building in the vicinity of the presidential palace was also raided by the protestors.

Following the protests that broke out throughout the country's capital on Sunday, Brazilian Supreme Court Judge Alexandre de Moraes demanded that the camp be immediately dismantled.

Additionally, cars are prohibited from entering the restricted area, but pedestrians can move around it freely, the report said.

Brazilian President Luiz Inacio Lula da Silva, who was sworn in and started his third term as president of Brazil on January 1, called the attacks on government buildings in Brasilia barbaric and ordered the use of federal forces to restore order in the capital.

It is worth noting that at the time of the riots, Lula was in Sao Paolo on an official trip. The Brazilian President told a press conference following the incident that "these vandals, whom we could call fanatical fascists, did what has never been done in the history of this country," adding that "all these people who did this will be found and they will be punished."

Furthermore, Lula stated "This genocidist [Bolsonaro] ... is encouraging this via social media from Miami," reaffirming that "everybody knows there are various speeches of the ex-president encouraging this."

The events prompted various countries and international organizations to voice their support for Lula, with many calling the riots an anti-democratic coup attempt.

Colombian President Gustavo Petro slammed Jair Bolsonaro supporters that raided earlier today Brazil's National Congress building and the presidential palace. Petro wrote a tweet expressing his support for Brazilian President Lula da Silva and his citizens.

In reference to the supporters of former far-right Brazilian President Jair Bolsonaro, Petro added that "the rights [right-wing supporters] have not been able to maintain the pact of non-violence."

Toda mi solidaridad a @LulaOficial y al pueblo del Brasil. El fascismo decide dar un golpe.

Las derechas no han podido mantener el pacto de la no violencia.

Es hora urgente de reunion de la OEA si quiere seguir viva como institución y aplicar la carta democrática.
