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. Videos and photos shared with Al Jazeera by residents showed grenade explosions, as well as horrific scenes of corpses lying in corridors, multiple bullet holes on residents doors, blood-stained mattresses and clothes, and blood flowing down staircases in the favela’s narrow alleys. But the Brazilian media widely applauded the operation they and Rio’s Civil and Federal Police force have said was a justified crackdown on drug trafficking and other violent crimes in the community.
