Boys play in the camp erected by an estimated 12,000 members of Brazil's Roofless Workers Movement (MTST) that invaded a 120 hectare (296 acres) plot of private land nearly two months ago to pressure the government to grant them ownership, in Itapecerica da Serra 38 kms (24 miles) southwest of Sao Paulo, May 6, 2007. Brazil's homeless and landless movements have gained momentum in recent weeks through a coordinated campaign of invasions of buildings and idle land aimed at securing property from the government. A court declared that the land in Itapecerica da Serra must be vacated and returned to its owner by May 7, but the squatters have vowed to resist any attempt to force them out.
