(AFP) – Alejandro was just 15 when he left home to join Colombia’s leftist FARC rebels — one of thousands of children recruited to fight the government during the deadly decades-long conflict. Three years on, he is back home, in school and readjusting to normal life thanks in part to a program based on the unique world vision of his Nasa Indian tribe, who live in the country’s southwestern Cauca department. “I joined the guerrillas because I was sick of being at home,” Alejandro, whose name has been changed for his own safety, told AFP.
