Outlaw militias torch 35 buses in Rio after crime boss is killed

 Suspected paramilitary militia members torched 35 buses and a train drivers' cabin in Rio de Janeiro Monday, paralyzing parts of the scenic Brazilian city after one of their leaders was killed in a police operation, officials said. 

The chaotic scenes erupted after an operation that state Governor Claudio Castro said killed the nephew and right-hand-man of a militia boss known as "Zinho."

Castro said the police had delivered a "hard blow to one of the largest militias in the west" of Rio, describing the nephew, who goes by the alias "Faustao" as a "known warlord."

Police subsequently arrested 12 people for suspected "terrorist actions" and city hall declared a level-three alert on its five-level scale, warning residents and tourists of possible "high-impact incidents."
