RIO DE JANEIRO -- v class="polopoly_embed" data-attribute="embed_code">

Brazil on Monday observed the anniversary of last year's uprising in the capital when thousands of supporters of former president Jair Bolsonaro invaded government buildings and called for a military intervention to remove President Luiz Inacio Lula da Silva from office.

Several demonstrations in defence of democracy were taking place across the South American country, hours after Federal Police carried out dozens of search warrants as part of its ongoing investigation targeting those responsible for the mayhem.
