A toy warehouse in Brazil's biggest city has caught fire, sending flames shooting high into the air.

Sao Paulo officials say there have not been injuries reported in the huge blaze. It's not yet clear what started the fire.

More than 20 fire trucks responded to the scene as 160 firefighters worked to control the Wednesday night blaze. Officials say the fire isn't spreading, but will take several hours to be fully under control.

The fire is happening away from tourist zones and isn't near the city's World Cup stadium. It's not expected to hamper matches.
