Argentine President Alberto Fernandez assailed the "coup attempt" by supporters of far-right former president Jair Bolsonaro who stormed Congress, the Supreme Court and the presidential palace.
Fellow South American leaders in Chile, Colombia and Venezuela deplored the mob action, and French President Emmanuel Macron tweeted his support for Luiz Inacio Lula da Silva, the leftist who took office as Brazil's leader a week ago.
"The will of the Brazilian people and the democratic institutions must be respected!" Macron tweeted.
US National Security Adviser Jake Sullivan tweeted that "President (Joe) Biden is following the situation closely and our support for Brazil's democratic institutions is unwavering."
Brazil's democracy, he added, "will not be shaken by violence."
The European Union's top foreign affairs official, Josep Borrell, tweeted that he was "appalled by the acts of violence and illegal occupation of Brasilia's government quarter by violent extremists today...
"Brazilian democracy will prevail over violence and extremism," he added.
The twitter account of Democrats on the US Senate foreign relations committee noted that the Brasilia ransacking came nearly two years to the day after supporters of then-president Donald Trump stormed the US Capitol in an attempt to overturn the 2020 election, leaving five dead.
"Trump's legacy continues to poison our hemisphere," the tweet said.
Around the Western hemisphere, reaction was particularly swift from leaders ideologically akin to Lula.
Mexican President Andres Manuel Lopez Obrador tweeted: "Lula is not alone, he has the support of the progressive forces of his country, of Mexico, of the American continent and of the world."
Chilean President Gabriel Boric decried "this cowardly and vile attack on democracy" and said the Lula government has Chile's "complete backing."
Venezuelan leader Nicolas Maduro, a leftist authoritarian, condemned what he called the "neofascist groups" seeking to unseat Lula.
