New Delhi: Indian PM Narendra Modi on Monday expressed concerns over the  rioting and vandalism against the state institutions in Brazil capital Brasilia.

"Deeply concerned about the news of rioting and vandalism against the State institutions in Brasilia. Democratic traditions must be respected by everyone. We extend our full support to the Brazilian authorities," Modi tweeted.

Police have arrested at least 400 people after supporters of Brazil's far-right former President Jair Bolsonaro stormed several government buildings in the country's capital Brasília, media reports said.

Three key buildings in the city-  the Supreme Court, the presidential palace and the congressional building - were stormed by the supporters of the former President of the country.

The incident recalled memories of Jan 6, 2021 invasion of the US Capitol building by supporters of  former president Donald Trump.
