Nearly 60 inmates have been killed in a wave of violence which has engulfed a number of detention facilities in Manaus, the capital of the northern state of Amazonas. Earlier this week, four different prisons reported violent riots, forcing the federal government to launch a special task force to address insecurity in the region. Over the last two years, tensions in northern Brazil have been brewing over the alleged expansion of criminal factions from the country’s south-east. They include the Sao Paulo-based First Capital Commando (PCC) and the Rio de Janeiro-based Red Commando (CV). Both groups are considered powerful organisations and are responsible for fuelling violence through territorial disputes in northern Brazil, especially from prisons where influential faction leaders are jailed. In northern Brazil, the CV is allied with the Northern Family (FDN), which is the main driving force of violence in the region.
