More than 12,000 landless Brazilian peasants and farmers have arrived at the outskirts of the capital, Brasilia, after marching nearly 125 miles (201 kilometers) to protest the slow pace of land reform.

Organizers say the demonstrators will stage protest rallies outside the U.S. embassy, Brazil's central bank and the finance ministry when they reach the center of Brasilia on Tuesday. The group is part of the Landless Workers Movement (MST), which backs Venezuelan President Hugo Chavez's alternative trade plans instead of the U.S. Free Trade Area of the Americas.

The landless protesters are calling for social revolution against Brazil's president and what they call U.S. imperialism in the region.

They are also protesting the government's failure to distribute land and resettle families of landless peasants.
