Two South Sudan Aid Groups Suspend Operations After Workers Killed Waakhe Simon Wudu JUBA , SOUTH SUDAN - Two aid groups have suspended operations in parts of eastern South Sudan after gunmen killed two of their workers late last week. The suspensions will make matters worse for thousands of citizens displaced by widespread flooding in Jonglei state. Annette Hearns, deputy head of the United Nations Office for the Coordination of Humanitarian Affairs (UNOCHA) in Juba, said the killings not only affected aid delivery to vulnerable people but caused more suffering for the families of the deceased. "We condemn this type of behavior. Our colleagues, South Sudanese citizens who are giving their ultimate sacrifice, these people are attempting to support children who are malnourished, the new mothers and help them receive the support they need to live," Hearns told VOA's South Sudan in Focus. .
