(AFP) – By the time Baba John escaped the tribal militia he had joined as an 11-year-old, he had long stopped counting the number of people he had killed. “I shot people. We all did,” said Baba John. “I received a gun and was told how to shoot and point the gun. I don’t remember how many I shot but there were many.” A murderous time for Baba John began with a life-or-death decision when a South Sudanese armed group, known as the Cobra Faction, attacked his village close to the eastern town of Pibor, nearly 400 kilometres (240 miles) north of the capital Juba.
