Brazilian police used tear gas canisters on Sunday to try to repel hundreds of supporters of far-right ex-president Jair Bolsonaro who invaded outside Congress in Brasilia.
The area around the Congress had been cordoned off by the authorities, but the Bolsonarists - who refuse to accept Lula's election - managed to break the security cordons.
Several dozen of them managed to climb the ramp of this building with modern architecture to occupy the roof.
The impressive images, reminiscent of the invasion of the Capitol in the United States, show a real human tide flowing towards Congress.
This brings together in the same building the Chamber of Deputies and the Senate.
Demonstrators appeared on the roof, but also on all the adjoining lawns, including that of the presidential palace of Planalto.
Jair Bolsonaro, who was narrowly beaten by Lula in the second round of the presidential election on October 30, left Brazil at the end of the year to join the United States.
