Supporters
of Brazilian far-right ex-president Jair Bolsonaro have stormed
Congress and police have used tear gas in an attempt to repel them.
The dramatic scenes came a week after left-wing veteran Luiz Inácio Lula da Silva's inauguration.
Supporters
of Mr Bolsonaro - who refuse to accept that he lost the election -
broke through barriers and entered the building in the capital,
Brasília.
Protesters - who smashed windows of the building - had been camping nearby.
Mr
Bolsonaro's supporters are calling for military intervention and the
resignation of Mr da Silva - better known as Lula - who defeated his
far-right rival in October's election.
Lula is currently on an official trip in São Paulo state.
In his inauguration speech, Lula vowed to rebuild a country in "terrible ruins".
He decried the policies of his predecessor, who went to the US to avoid the handover ceremony.
