RIO DE JANEIRO, Brazil (CNN) — Some 2,000 police officers patrolled the streets of Rio de Janeiro Sunday after a bloody confrontation between rival drug gangs and authorities that killed 14 over the weekend, including two police officers.
Two suspected drug traffickers were killed and four were arrested in Sunday's operations by Rio de Janeiro's military police, the official news agency Agencia Brasil reported.
But the atmosphere in general appeared calm in the slum known Morro dos Macacos in northern Rio, where the day before crossfire between two gangs left 12 dead, including two police officers who died when their helicopter was shot out of the sky. Residents had also set eight buses on fire during the clashes in an attempt to divert the attention of police.
"This was truly one of the worst incidents of this type," one local resident told CNN en Español, who declined to give his name for fear of his safety. "It was like a scene from a real war. It was like the world would end, lots of bullets, lots of noise."
The violence comes two weeks after Rio, Brazil's second largest city, celebrated winning the 2016 Olympic Games.
