Brazil's soldiers guard the entrance of the Providencia hillside slum in Rio de Janeiro, Brazil, on Saturday, March 11, 2006. The occupation by some 1,600 troops came in response to the robbery of 10 assault rifles and one pistol stolen from army barracks last Friday by seven gunmen wearing army-issue camouflage gear and ninja masks.

None of the weapons has been recovered, but many in Rio have long yearned for the military to take over the city's shantytowns, which are controlled by armed drug gangs who frequently light up the night sky with tracer bullets.
