Residents play soccer at the Mare slums complex during a police operation in Rio de Janeiro March 30, 2014. The federal troops and police occupied the Mare slums complex on Sunday to help quell a surge in violent crime following attacks by drug traffickers on police posts in three slums on the north side of the city, government officials said. Less than three months before Rio welcomes tens of thousands of foreign soccer fans for the World Cup, the attacks cast new doubts on government efforts to expel gangs from slums using a strong police presence. The city will host the Olympics in 2016. REUTERS/Sergio Moraes (BRAZIL - Tags: CRIME LAW SPORT SOCCER) less
