Brazilian authorities say police have taken control of the largest slum in Rio de Janeiro, which has been occupied by drug traffickers for decades. The police invaded Rocinha early Sunday morning. The action is part of a police campaign to stabilize Rio's security before its hosts the 2014 World Cup and the 2016 Olympics. Rocinha is built on a steep hillside near some of Rio's richest neighborhoods. Brazilian officials say more than 1.5 million people in Rio de Janeiro live in 1,000 slums spread throughout the city.
