Thousands of protesters took to the streets of SÃ£o Paulo, Rio de Janeiro and other Brazilian cities. And some of the protests have turned violent.
Things got ugly in SÃ£o Paolo last night when 5,000 demonstrators blocked traffic and vandalized buildings in the city. Police used teargas and rubber bullets to disperse them.
So what's all the commotion about? A simple urban concern: a hike in bus fare, the equivalent of just 10 US cents.
Vincent Bevins, a reporter with the LA Times in SÃ£o Paulo, was on the scene when the tear gas came out.
