Troops target drugs gangs in Rio de Janeiro slum

Police in Brazil say they have completed an operation to clear Rio de Janeiro's biggest slum, Rocinha, of drug gangs.

Officers are trying to clean up Rio's shantytowns ahead of the 2014 World Cup and 2016 Olympics.

Since 2008, they have occupied some 20 slums, or favelas, to drive out the dealers who controlled the areas.

Paulo Cabral reports.
