Amnesty International is gravely concerned about the rapidly deteriorating human rights and humanitarian situation in South Sudan’s now over four-year-old internal armed conflict. Since the conflict began on 15 December 2013, we have continuously documented violations of international human rights and international humanitarian law, including the deliberate killing of civilians, sexual violence on a massive scale, the denial of food as a weapon of war, widespread destruction of private and public property, large-scale forced displacement, prolonged and arbitrary detentions, torture and other inhumane treatment, and enforced disappearances.
