Brazil's police and military are continuing their crackdown on Rio's powerful organized criminal gangs.
As Al Jazeera outlines in this TV report, at least 45 people have died and another 192 were detained in fighting that left vehicles burned and schools closed in the northern part of the city where the fighting is concentrated. Police and military personnel have surrounded the favela known as Alemao, after swarming Villa Cruzeiro in the last few days.
Recent media reports have blamed the fighting on Comando Vermelho, a nationwide syndicate that began in the country's chaotic prison system.
