Violence in South Sudan's Upper Nile displaces 9,000 -U.N. agencies

JUBA (Reuters) - Violence in South Sudan's Upper Nile state has killed an unknown number of people and displaced just over 9,000, some of whom are hiding in swamps, United Nations agencies said on Wednesday.

Violence is rampant in parts of South Sudan where clashes triggered by local disputes over grazing areas, water, cultivation grounds and other resources often turn deadly.
