Police in Brazil have used tear gas to break up protesters on the second day of a metro strike that has left Sao Paulo's transport in chaos.

Nearly half of the stations were closed and there was gridlock on the streets of Brazil's largest city, which will host the opening match of the World Cup next Thursday.
