The dramatic scenes - which saw thousands of protesters clad in yellow Brazil football shirts and flags overrun police and ransack the heart of the Brazilian state - come just a week after Lula's inauguration.Mr Bolsonaro has repeatedly refused to accept that he lost October's election and last week left the country instead of taking part in inaugural ceremonies, which would have seen him hand over the iconic presidential sash.The 67-year-old - who is believed to be in Florida - condemned the attack and denied responsibility for encouraging the rioters in a post on Twitter some six hours after violence broke out.Speaking before he arrived in Brasilia, Lula said there was "no precedent in the history of our country" for the scenes in Brasilia and called the violence the "acts of vandals and fascists".Video shared by the Brazilian outlet O Globo showed some officers laughing and taking photos together as demonstrators occupied the congressional campus in the background."
