Aid group Doctors Without Borders said it has been forced to suspend work in a volatile part of South Sudan because of attacks against his staff, as violence between rival tribes surges in the area, AP reported. The group, also known as Medecins Sans Frontieres, said Friday that armed men stole medical equipment from one of its health clinics twice this month in Jonglei state. Staff members have also been attacked while delivering aid, the organization said. Heavily armed southern tribes have had to compete for scarce water and pasturage in the area. Clashes reignited more than a year ago and intensified beyond traditional cattle raids to include attacks on civilians across the entire south. Aid agencies have said some 2,500 people were killed and 350,000 others were displaced in 2009 due to the violence. -- SPA
