(Bloomberg) – Hundreds of South Sudan’s children have been killed or maimed fighting their peers during the country’s two-year civil war, in which as many as 16,000 minors have been forced to participate, the United Nations Children’s Fund said. Children “have been used to fight and perpetrate violence against other children and civilians, or serve as cooks, cleaners or to carry heavy loads while on the move,” Unicef said Thursday in a statement e-mailed from the oil-producing nation’s capital, Juba.
