Violence in the streets of Sao Paulo as the fires of rage burn over the World Cup.
Protesters have taken to the streets in angry protest over government overspending on the event.
Security forces are doing what they can to contain the unrest.
The protests are expected to grow in size before Brazil plays Croatia later in the day.
The stakes will be high -- not just on the soccer field. The tournament's success may also impact President Dilma Rousseff's chances for re-election in October, as well as Brazil's flagging reputation among investors.
