The majority of Latin American countries are run by left wing leaders and we’ve been taking a look at what they’ve been saying about what’s been happening in Brazil.

Mexico's President Andres Manuel Lopez Obrador called the riot a coup attempt by what he called “the conservatives of Brazil egged on by the leaders of oligarchic power” adding that President Luiz Inácio Lula da Silva could could count on Mexican support.

Colombia’s leader also described what’s been happening in Brasilia as a coup. President Gustavo Petro tweeted the Organization of American States "should apply the democratic charter", which are rules governing democracy in Latin America.

Meanwhile, Bolivia's President Luis Arce tweeted “The fascists will always want to take by force what they did not achieve at the ballot box”.

Brasilia is a big city – but many of the rioters who wreaked havoc on Sunday are not local residents. Authorities say more than 100 buses arrived in the Brazilian capital carrying rioters who went on to loot Congress, the Supreme Court and the presidential palace.

This may help authorities find out who is financing the protests.

Brazilian Justice Minister Flavio Dino said the police already know who hired the buses and will now investigate all passengers who were on them.

Some of the protesters who came to the capital on Sunday have also been camping outside army barracks across Brazil, they want a military intervention against Luiz Inácio Lula da Silva's government.

These camps are well organised and some supporters of former President Jair Bolsonaro have been living in them since October’s election. The Brazilian government say they will now dismantle all camps and prosecute those responsible for financing them.

Congress, the Supreme Court and presidential palace were left in ruins on Sunday after a sea of protesters invaded the monumental buildings on Sunday.

Videos circulating on social media showed protesters trashing offices, smashing windows and doors, flipping furniture, and tossing computers and printers to the ground.

Rioters also damaged artworks and historic objects - a Emiliano Di Cavalcanti painting was punctured and an iconic statue outside the Supreme Court was vandalised, according to AP.

Police have regained control of the site and have made hundreds of arrests.

President Luiz Inacio Lula da Silva, who took office a week ago, viewed the damage at the presidential palace and the Supreme Court earlier.

He said he plans to work from the palace today despite the destruction.

Here's a closer look at the damage:

The protesters involved in the unrest in Brasilia used codes in social media to plan Sunday's invasion.

Since former President Jair Bolsonaro lost the election, thousands of his supporters have used online chat in WhatsApp and Telegram to arrange their protests.

The rioters had planned for a protest this Sunday in the capital Brasilia, one week after president Luiz Inácio Lula da Silva took office. Ads offering free transportation from different parts of the country to Brasília were shared on social media.

But behind the scenes, several users had been calling on others to join something else: "Selma's Party". "Selma" is a play with the word "selva", which means "jungle" in Portuguese, a word used by the Brazilian military as a greeting, and as a warning.

On Thursday, four days before the riot, a video about "Selma's Party" went viral in Telegram groups. In it, a man describes the "ingredients" necessary for the "party" - union and organisation.

As people arrived for the protest on Saturday, a man recorded a video saying the "'patriots had to be brave" and leave the military barracks. Instead, he said, everyone should go to Praça dos Três Poderes (Three Powers Square). This video also went viral.

One image shared in several groups shows people inside a map of Brazil. Below, a text reads: "Time to take it back".

On Sunday, thousands of protesters ransacked Brazil's Congress, presidential palace, and Supreme Court in Brasilia.

The demonstrators refuse to accept that former President Jair Bolsonaro lost October's election, and want to see military intervention and the resignation of President Lula.

Dozens of messages shared by supporters of Jair Bolsonaro on Telegram throughout the week appeared to anticipate the storming of government palaces in Brasilia.

In a message sent on Friday, a man offers available spaces in "free buses" with "everything for free: water, coffee, lunch, dinner".

Brazilian authorities are under scrutiny for an alleged lack of plans to avoid the crisis.

In another message, Bolsonaro fans ask "hackers and IT experts" to "invade all government systems" and armed men to "protect the patriots".

They also invited reservists from the "military and police" to "share tactic experience and lead the seizure of Brasilia and its phoney government".

On Saturday, a man shared a video showing government buildings with this caption: “Tomorrow is the day. By the way, from now on, emotions will be strong”.

“The coup is not by president Bolsonaro. The coup is not by the Armed Forces”, reads another message.

“The coup is by the Brazilian people and will be fatal."

As we've been reporting there has been international condemnation of scenes in Brasilia, after thousands of Jair Bolsonaro's supporters stormed Congress and other public buildings.

The capital's distinctive National Congress building is the legislative third of the Three Powers Plaza in Brasilia.

Protesters also stormed the other two branches in the plaza - known as the Planalto Palace (presidential office) and the Supreme Court.

Photos show the extent of the damage in these three buildings - various window panels have been broken, furniture has been overturned and debris is noticeably scattered on the ground.

President Luiz Inacio Lula da Silva has been to all three branches of Brazil's government to inspect the damage following the violent invasion.

A bit of history for you about Brazil's capital.

Back in the late 1950s Brasilia was a city built at a rapid pace - three-and-a-half years.

The idea was to create an image of a modern Brazil away from the mega cities of Sao Paulo and Rio de Janiero.

In 1960 Brasilia replaced Rio de Janeiro as the federal capital of Brazil and seat of government.

Many of the Brasilia's most striking buildings were designed by architect Oscar Niemeyer - noted with his trademark use of concrete and curves.

Among them were the National Congress, with its concave and convex domes symbolising the two houses of the legislature, and the city's cathedral with 16 columns coming together to represent hands outstretched to heaven.

Political leaders around the world have condemned Sunday's events in Brasilia, throwing their support behind Brazil's new President Lula.

US President Joe Biden said: "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."

French President Emmanuel Macron said the will of the Brazilian and the country's democratic instructions must be respected, adding his government offers President Lula France's unconditional support.

Canadian Prime Minister Justin Trudeau said that "respecting the democratic will of the people is paramount in any democracy", while German Chancellor Olaf Scholz described the destruction as an "attack on democracy that cannot be tolerated".

"China closely follows and firmly opposes the violent attack", Chinese foreign ministry spokesman Wang Wenbin said, throwing Beijing's support behind "measures taken by the Brazilian government to calm the situation, restore social order and safeguard national stability".

Leo Puglia, a teacher of history and sociology in Brazil, told the BBC's Newsday programme that Bolsonaro's supporters are "looking for a coup d'etat, because that is what Bolsonaro promised them, but he did not deliver it".

In his view, Bolsonaro escaping to the United States made his supporters "more radical, because they don't believe in corporate media.

"They just get information from WhatsApp and Bolsonaro's social media, so they are really disconnected from reality.

"They believed that Bolsonaro would win the election easily, it did not happen, and then when Lula was elected, they believed that it would happen militarily, a coup d'etat, and Bolsonaro would become dictator of Brazil."

The authorities have taken control of Brazil's presidential palace and other government buildings and are beginning to assess the damage inside.

UK Prime Minister Rishi Sunak has condemned "any attempt to undermine the peaceful transfer of power and the democratic will of the people of Brazil".

Writing on Twitter, Sunak says, external Brazil's President Lula has the UK's "full support", adding that he looks forward to "building on our countries' close ties in the years ahead".

As we've been reporting Brazil's President President Luiz Inacio Lula da Silva, known as Lula, travelled to Brasilia and visited the site of the attack to inspect the damage.

He has vowed to punish those responsible for the attacks on Brazil's Congress and other key federal buildings.

Speaking before he arrived in Brasilia, Lula said there was "no precedent in the history of our country" for the scenes in the capital and called the violence the "acts of vandals and fascists".

And he took aim at security forces whom he accused of "incompetence, bad faith or malice" for failing to stop the demonstrators.

The UK government has pledged its full support to Brazil's government and President Lula, following the attack.

Writing on Twitter last night, external, Foreign Secretary James Cleverly said the "violent attempts to undermine democracy in Brazil are unjustifiable".

Police were initially "very patient" and "not very aggressive" with protesters in Brasilia before the attack took place, a Brazilian journalist has said.

Carlos Alexandre de Souza, political editor of the Correio Braziliense newspaper, says officers attempted to keep the crowds away from the federal government buildings and prevent them from "destroying everything".

But he tells BBC Radio 4's Today programme that police are still working to keep people away from the buildings that were attacked, as many attempt to see the damage that has been inflicted.

"The local police took too long to control the situation, and there have been many consequences since then," de Souza says.

Conspiracies pushing the idea that the election in Brazil was rigged - and that Bolsonaro was the real winner - have been circulating among his supporters online for weeks in the build-up to what happened in Brasilia.

It means that the spotlight is once again on social media platforms.

What role did they play? And could they have quelled misinformation online that may have contributed to the protests?

Twitter in particular finds itself the subject of scrutiny. After Elon Musk took over, the company laid off staff including those in Brazil whose role was to tackle misinformation around the election.

Twitter and Musk have repeatedly said they are tackling the most harmful content on the site.

But it's hard not to draw a comparison with the sotrming of the US Capitol on 6 January two years ago - also driven by misinformation.

Narratives suggesting votes are rigged spread online and build over several months, fanned by influential political figures. They then inspire hardcore supporters to take action based off evidence-free ideas.

On the BBC's Americast podcast this week, we discussed the legacy that those Capitol riots in the US have left behind. The conspiracies that played out that day have not just disappeared, they've continued to spiral beyond the US.

In the hours after rioters temporarily took over Brazil's most important democratic institutions, residents of an affluent Bolsonaro-voting area of Brasilia were uneasy.

"It's a sad, sad day for Brazil. Unfortunately, I'm not surprised at all," said Victor, 28, a cafe kiosk worker.

He said he had been expecting some sort of similar action before New Year's Eve, when President Luiz Inácio Lula da Silva was inaugurated.

Outside the famous Our Lady of Fatima church just around the corner, a few people were praying.

One of them told me it was a minority of people who wanted the riots and violence.

"But that's not what democracy is about. There will be winners and losers," said Oswald, 50.

"Winners will govern the country, losers have to accept, and the country will continue to grow and develop.”

On Sunday, thousands of supporters of Brazil's ex-president Bolsonaro stormed official buildings in the country.
