RIO DE JANEIRO — At least 2,000 Brazilian police officers patrolled this coastal city Sunday as officials pledged to hold a violence-free 2016 Olympics despite bloody drug gang shootouts that left 14 people dead.
An hours-long gun battle Saturday between rival gangs in one of the city's slums killed at least 12 people and injured six. A police helicopter was shot down and eight buses set on fire during the incident.
Police said Sunday that they had killed two suspected drug traffickers in overnight clashes near the Morro dos Macacos ("Monkey Hill") slum where the gangs fought for territory. But the area was largely peaceful.
Two officers died and four were injured Saturday when bullets from the gang battle ripped into their helicopter hovering overhead, forcing it into a fiery crash landing on a soccer field. Officials said they did not know whether the gangs targeted the helicopter or it was hit by stray bullets.
