SAO PAULO, Brazil -- A small protest in Sao Paulo has seen demonstrators block a commuter train line with burning tires.
They also set fire to at least two nonresidential buildings nearby.
About 150 demonstrators took the action Thursday to protest the eviction of slum dwellers from an area where authorities say they illegally built shacks in recent weeks.
Police firing tear gas have scattered the protesters, and fire fighters say they've controlled the blazes.
Brazil has seen nearly constant protests since June, when mass anti-government demonstrations broke out amid frustration with poor public services despite heavy taxes.
Since the end of June, the protests have grown fragmented and smaller.
