An estimated 8,000 landless activists converged on Brazil's capital this week to demand land reform.
The demonstrators surrounded the central bank in Brasilia Thursday, carrying a list of demands for delivery to a bank official.
The Reuters news agency quoted one activist as saying there could be another fight over the issue in five to six months unless more public money is provided to speed up land reform.
The protest took place just days after hooded gunmen killed five land reform activists on a farm in the southeastern state of Minas Gerais.
Brazil has one of the greatest disparities in land ownership in the world, with a small number of wealthy ranchers owning the vast majority of the land.
