Around 1,500 people have been detained in Brazil after supporters of former President Jair Bolsonaro stormed Congress, the presidential palace and the Supreme Court. 

The unrest erupted just a week after President Lula da Silva was sworn in.

He called the attack a "terrorist act" and promised that the perpetrators would be punished.

Meanwhile, Jair Bolsonaro, who is in Florida, was admitted to hospital with abdominal pain. 

Against this backdrop, tens of thousands took to the streets of Brazil's largest city, Sao Paulo, in support of democratic values.

"This is total absurdity, the worst moment in our history since the dictatorship of 1964. I think everyone was horrified by the footage we saw in the National Congress. This here is our response. The struggle now is to support the government that was democratic elected and we will not leave the streets, that is the message," said Sao Paulo resident Neto Duarte.

All three Brazilian authorities condemned the attacks on state institutions

"It was an attempted coup and I expect the law to be applied to all those involved. That's what I expect and I came here to fight for it," said Vera, a Sao Paulo resident.
