RIO DE JANEIRO, BRAZIL - MARCH 29:  People gather in an impoverished section of the unpacified Complexo da Mare slum complex, one of the largest 'favela' complexes in Rio, on March 29, 2014 in Rio de Janeiro, Brazil. The Brazilian government is deploying federal forces tomorrow to occupy the group of violence-plagued 'favelas' ahead of the June 12 start of the 2014 FIFA World Cup. The group of 16 communities house around 130,000 residents and have been dominated by drug gangs and militias. Mare is located close to Rio's international airport and has been mentioned as a likely pacification target for the police amid the city's efforts to improve security ahead of the 2014 FIFA World Cup and Rio 2016 Olympic Games.
