Washington, Muharram 7, 1436, Oct 31, 2014, SPA -- Brazilian police on Thursday found the bodies of five men inside a car abandoned in one of the slums of Rio de Janeiro. At least one body was decapitated. Police said they were investigating what seems to be retribution by one drug gang against members of another gang for the death of a teenage boy in the same area earlier this week. A message was written on a pizza box left on the car, saying, “A life for a life,” and “you killed an innocent.” Violence in the city’s already turbulent slum neighborhoods has been rising. Gangs are increasingly staging attacks against each other and against police who are attempting to create permanent posts in many slums before the 2016 Olympics. --SPA 14:26 LOCAL TIME 11:26 GMT www.spa.gov.sa/w
