(HRW) – In early 2014, just a month after war had broken out between South Sudan’s government and the armed opposition led by Riek Machar, the former vice president, government forces tore their way southward through Unity state, burning villages and displacing thousands of civilians into swamps and other hard-to-reach areas where over the next months they would struggle to survive. Civilians fled for days as one village after another was attacked, and many told us of sexual violence, hunger, and extensive looting by government forces and their allies.
