Brazil’s President Jair Bolsonaro has come under criticism for joining protesters demanding that restrictions on movement introduced to stop the spread of coronavirus be lifted.
Mr Bolsonaro has clashed in recent weeks with state governors who have imposed lockdowns, denouncing the measures as “dictatorial”.
As of Sunday, Brazil had more than 38,000 confirmed cases, the highest number in Latin America.
More than 2,400 people there have died.
President Bolsonaro addressed a crowd of a few hundred supporters outside army headquarters in the capital, Brasilia, on Sunday.
He said the protesters were “patriots” for defending individual freedoms.
