YAMBIO, South Sudan (AP) — More than 300 child soldiers were released Wednesday by armed groups in South Sudan, the second-largest such release since civil war began five years ago. The "laying down of the guns" ceremony for 87 girls and 224 boys was the first step in a process that should see at least 700 child soldiers freed in the coming weeks, the United Nations said. Putting down weapons and rejoining normal life is just the "beginning of the journey," said the head of the U.N.
