A major police raid in Rio de Janeiro has resulted in the deaths of more than 130 people, making it the most deadly operation in Brazil’s history. The mission aimed at dismantling the Red Command gang has triggered widespread criticism over the use of excessive force. Local residents, activists and international rights groups are demanding transparent investigations and justice for the victims. Brazil’s president has expressed shock over the scale of the bloodshed, as humanitarian organisations urge major reforms in the country’s policing and accountability systems.
