Rio de Janeiro, Brazil – At least 25 people have been killed after hundreds of heavily armed police stormed into one of Rio de Janeiro’s largest slum areas, reportedly targeting drug traffickers. Local media showed live footage of seven armed young men hopping through the roofs of North Zone’s Jacarezinho favela in the early hours of Thursday morning, as bulletproof helicopters hovered over them. The report said the “extremely suspicious criminals” were attempting to escape from the police. Two passengers on the metro were hit by a stray bullet and one police officer was killed.
