The army was deployed after a government ministry was set alight in the worst anti-government violence in Brasilia for four years.
Protesters demanding the resignation of Brazil’s President Michel Temer have staged running battles with police in the capital Brasilia.
The army was sent onto the streets after the Agriculture Ministry building was set alight.
Police fired volleys of tear gas, stun grenades and rubber bullets to stop thousands of demonstrators as they marched on Congress.
The protesters want an end to the government’s austerity programme. They are also furious at the corruption scandal which has now seen Temer accused of paying off a potential witness.
One protester was shot and wounded, while other serious injuries were reported. It was the most violent protest in the capital for four years.
